Soon after assuming the office of the presidency in January 2017, President Donald Trumpfiled preliminary paperwork that laid the groundwork for re-election in 2020.
Currently, 16 Democratic contenders are lined up to challenge Trump — making for one of the largest and most diverse primary fields in recent history. So far, several Democrats have also dropped out of the race.
On November 7, The New York Times reported that former New York Mayor Michael Bloomberg is filing preliminary paperwork to run for president as he considers entering the crowded Democratic primary field.
The most recent candidates to drop out are Mayor Bill de Blasio of New York City, who quit the race on September 20, and former Rep. Beto O'Rourke, who ended his campaign on November 1.
Former Vice President Joe Biden, six current and former US Senators, three current and former members of the House of Representatives, two mayors (three if Bloomberg runs), one governor, two businessmen, and one prominent author are now in the race.
Trump is also facing opposition within his own party. Former Massachusetts governor Bill Weld, and former GOP congressman and conservative radio host Joe Walsh are both challenging Trump in the Republican primary. Former South Carolina governor and Rep. Mark Sanford, who was also challenging Trump in the GOP primary, also ended his bid on November 12.
Here are all the major party candidates running for president in 2020:

Former New York City Mayor Michael Bloomberg
On November 7, The New York Times reported that former New York City Mayor Michael Bloomberg is possibly making a late entrance in the 2020 Democratic primary and planning to file to run in the Democratic primary presidential primary in Alabama.
Bloomberg will have to work quickly to get his campaign off the ground just three months out from the Iowa caucus on February 2, and New Hampshire primary on February 9, but he has the luxury of being able to self-fund his campaign.
Citing sources close to Bloomberg, The Times reported that in recent months, he's become increasingly concerned over former Vice President Joe Biden's lackluster fundraising and slipping performance in the polls.
He's also worried about the rise of Sens. Bernie Sanders and Elizabeth Warren, two leading Democratic candidates who have both proposed hefty taxes on billionaires Bloomberg and greater regulation on big business.
Former Tea Party congressman and conservative radio show host Joe Walsh.
Walsh, who served one term in Congress from 2011 to 2013, announced he would launch a primary challenge against Trump on August 25.
Speaking to ABC's George Stephanopoulos, Walsh said, "We've got a guy in the White House who is unfit, completely unfit to be president and it stuns me that nobody stepped up, nobody in the Republican party stepped up."
While Walsh initially voted for and supported Trump, he has since become one of Trump's most vocal critics, calling Trump's behavior "narcissistic" and "childish."

Billionaire financier and liberal activist Tom Steyer
Steyer, who is 62 and based in San Francisco, made his fortune as an investor and hedge fund manager — but has since focused his efforts on advancing progressive causes with two organizations: Need To Impeach, and NextGen America, the latter of which is focused on combating climate change.
In January 2019, Steyer said he did not plan to run for president and would be "dedicating 100% of my time and effort in 2019 towards Mr. Trump's impeachment and removal from office."
But Steyer since changed his mind, making a late entrance into the 2020 field with a video announcement on July 9 and planning to spend at least $100 million of his own money on his campaign.
Read more about Tom Steyer's campaign.
Former Rep. Joe Sestak of Pennsylvania
Sestak, a former two-term congressman from Pennsylvania and Navy admiral, became the 25th candidate to join the 2020 field on June 22, missing the deadline to qualify for the first Democratic debates.
After retiring from the House in 2010, Sestak unsuccessfully ran for US Senate in Pennsylvania both in 2010 and 2016, famously walking over 400 miles across Pennsylvania during his second Senate run.
In his announcement video, Sestak emphasized his 31 years of military service as an important qualification to serve as president, saying, "when faced with the decision on whether to use our military, our commander in chief will know how it will end before deciding if it is wise to begin."
Read more about Joe Sestak's campaign.
Governor Steve Bullock of Montana
Bullock, the Democratic governor of Montana, announced he's running for a president on May 14th, the 22nd Democratic contender and the third governor to join the field.
In an announcement video posted online Tuesday morning, Bullock highlighted his work passing bipartisan legislation to ban corporate money in Montana's elections as governor.
Bullock argues he brings unique strength to the table as a Democratic governor who was re-elected the same year Trump won his state by 20 points — and has since achieved progressive victories including expanding Medicaid and freezing university tuition in the spring 2019 Montana legislative session.
Read more about Steve Bullock's campaign.
Senator Michael Bennet of Colorado
Bennet, the 21st Democrat and seventh US senator to announce a 2020 presidential campaign, is currently serving his second elected term as Colorado's senior senator.
"I think this country faces two enormous challenges,"Bennet said about his decision to run on "CBS This Morning".
"One is a lack of economic opportunity and mobility for most Americans and the need to restore integrity to our government."
As a senator, Bennet has mainly been known for his quiet intellect, bipartisan legislative achievements, and affable demeanor.
But this January the usually demure Bennet went viral for an uncharacteristically fiery and passionate speech on the Senate floor slamming Sen. Ted Cruz for shedding "crocodile tears" over the then-ongoing government shutdown.
Read more about Michael Bennet's campaign.
Former Vice President and Senator Joe Biden of Delaware
After months of teasing a presidential run, Biden officially entered the race with a video announcement on April 25, the 20th Democratic candidate to join the Democratic field.
"...if we give Donald Trump eight years in the White House, he will forever and fundamentally alter the character of this nation, who we are, and I cannot stand by and watch that happen,"Biden said in his announcement.
Biden, 77, enters the race as a frontrunner with unparalleled name recognition among Democratic primary voters, leading nearly every single pre-primary poll conducted before he officially declared his candidacy.
Biden, who served as President Barack Obama's Vice President for eight years and a US Senator for 36, is drawing on his blue-collar roots and close ties to organized labor to directly challenge Trump in Rust Belt states he carried in 2016.
The former vice president, who has been in politics for almost 50 years, will still have to contend with some of the more controversial aspects of his record, and make the case for his candidacy in the largest and most diverse Democratic presidential primary field in recent history.
Read more about Joe Biden's campaign.
Former Governor Bill Weld of Massachusetts
Weld, who served as Massachusetts' governor in the 1990s and was more recently on the Libertarian Party ticket in 2016 as presidential candidate Gary Johnson's running mate, announced his campaign on April 15.
"It is time for patriotic men and women across our great nation to stand and plant a flag. It is time to return to the principles of Lincoln — equality, dignity, and opportunity for all," he said in his announcement statement.
"There is no greater cause on earth than to preserve what truly makes America great. I am ready to lead that fight."
Read more about Bill Weld's campaign.
Senator Bernie Sanders of Vermont
Bernie Sanders will be competing for the Democratic nomination for the second time, he announced on February 19.
The 77 year-old Vermont senator, who is officially an independent but caucuses with Democrats in Congress, and former Burlington mayor has been a progressive stalwart for decades and built up a strong base of support for his platform in 2016 despite falling short to Hillary Clinton in the primary.
"Our campaign is about more than beating Donald Trump," he said in his announcement video. "It's about transforming our country and creating a government based on the principles of economic, social, racial, and environmental justice."
This time around, Sanders will face much stiffer competition in a Democratic field that could hold over 20 candidates — many of whom are running on platforms that emphasize his signature issues of reducing income inequality and the power of big corporations in America.
Read more about Bernie Sanders' campaign.
Senator Amy Klobuchar of Minnesota
On February 10, three-term US Senator from Minnesota Amy Klobuchar became the 12th Democratic candidate and 6th woman to jump into the 2020 field.
In true Minnesota fashion, Klobuchar announced her candidacy at an outdoor event during a blizzard, giving her speech without a hat, gloves, or a teleprompter.
Klobuchar is counting on her reputation as a measured, pragmatic moderate with a "Minnesota nice" demeanor to dominate among Midwestern voters — and pose a stark contrast to President Donald Trump.
Her campaign rollout may be hampered, however, by recent reports published in BuzzFeed News and the Huffington Post detailing alleged mistreatment and humiliation of her staff. According to one report, three people turned down the job of running her campaign over those allegations.
Read more about Amy Klobuchar's campaign.
Senator Cory Booker of New Jersey
Cory Booker, the 11th Democrat to jump into the race, officially announced his candidacy for President on February 1.
Booker has served in the US Senate since 2013, and is known for his liberal voting record and emphasis on social and criminal justice issues. He played a key role in passing a large bipartisan criminal justice bill, the First Step Act, in December.
Before being elected to the Senate, booker served two terms as Mayor of Newark, New Jersey where he still resides. He holds a degree from Stanford University, where he played on the football team, and a law degree from Yale University.

Motivational speaker, author, and friend of Oprah Winfrey Marianne Williamson
Marianne Williamson, a motivational speaker, New York Times best-selling author, and one-time congressional candidate with a substantial following announced her candidacy for president on Monday night.
Williamson, the 10th Democratic candidate to jump into the race, began speaking and writing self-help books rooted in New Age spirituality in Los Angeles in the 1980s. She's also been heavily involved in AIDS awareness and advocacy efforts.
A 1992 appearance on Oprah Winfrey's show helped launch her into Hollywood's elite class as the preferred spiritual guide for many in the entertainment world.
Her first foray in politics was an independent run for Congress in California's 33rd congressional district in 2014. She ended up losing to current Rep. Ted Lieu, but is now launching a bid for the highest office in the land.

Mayor Pete Buttigieg of South Bend, Indiana
Pete Buttigieg, mayor of South Bend, Indiana, announced his candidacy for the Democratic nomination on January 23, 2019 via a video and email sent to his supporters.
The mayor just turned 37, making him the youngest entrant (so far) in the battle for the Democratic nomination. Buttigieg is also the only openly gay candidate to date in the running.
Along with Rep. Tulsi Gabbard of Hawaii and Rep. Seth Moulton of Massachusetts, Buttigieg is one of three military combat veterans running for the Democratic nod, having served with the US Naval Reserve in Afghanistan in 2013.
In the video, Buttigieg, who is making the jump from city to national politics, said he belongs to "a generation that is stepping forward right now."
"We're the generation that lived through school shootings, that served in the wars after 9/11, and we're the generation that stands to be the first to make less than our parents unless we do something different," he said in his announcement video.

Senator Kamala Harris of California
Harris made her announcement on Martin Luther King Day, or January 21, via Twitter and her campaign website.
The Democratic senator for California is currently serving her first term in the Senate, similar to former President Barack Obama, who was initially criticized for his inexperience after he announced his 2008 presidential campaign as a first-term senator.
Prior to her role in the Senate, Harris was California's attorney general and served as the district attorney of San Francisco.

Former Housing and Urban Development Secretary Julián Castro
Julian Castro declared his candidacy on January 12 in a widely publicized announcement event in San Antonio, Texas, his hometown and where he served as mayor for five years.
Castro's official announcement came weeks after his brother had revealed the news during an interview with Stephen Colbert in December.
Under Castro's tenure, HUD expanded lead safety protections in federally assisted housing, worked to reconstruct communities affected by natural disasters under a $1 billion National Disaster Resilience Competition, and fulfilled the Fair Housing Act.
Read more about Julian Castro's campaign.
Representative Tulsi Gabbard of Hawaii
Gabbard announced her candidacy on January 11 in an interview with CNN's Van Jones.
The Hawaii representative has been in Congress since 2012, and has been at times a rising star for progressives but also sometimes challenging to the rest of her party. Her positions on foreign policy, in particular, have at times put her at odds with many on the left over the past year or two.
Read more about Tulsi Gabbard's campaign.
Senator Elizabeth Warren of Massachusetts
On a video posted to her website on December 31, 2018, Massachusetts Senator Elizabeth Warrenannounced that she was launching an exploratory committee for a presidential run in 2020.

Read more about John Delaney's campaign.
President Donald Trump
President Donald Trump is seeking reelection in 2020. He announced his intentions to do so just days into his first term, on January 20, 2017.
Dropped out: former South Carolina governor and Rep. Mark Sanford
Sanford announced on September 8, 2019 that he would launch a primary challenge to Trump, which marked the third challenge from within the president's party.
The former congressman lost a primary in 2018 after emerging as a vocal critic of Trump, who in turn encouraged voters to vote against him.
In a "Fox News Sunday" interview announcing the challenge, Sanford said he thinks "we need to have a conversation on what it means to be a Republican."
"I think that as a Republican Party we have lost our way," he added. After Stanford's long-shot bid failed to gain any traction, he dropped out of the race on November 12.
Read more about Mark Sanford's campaign.
Dropped out: Former Congressman Beto O'Rourke of Texas
Beto O'Rourke formally announced his candidacy for president on March 14, ending months of speculation over his presidential plans.
"The only way for us to live up to the promise of America is to give it our all and to give it for all of us,"he said in a video announcing his candidacy alongside his wife Amy.
"The interconnected crises in our economy, our democracy, and our climate have never been greater," O'Rourke added. "And they will either consume us, or they will afford us the greatest opportunity to unleash the genius of the United States of America."
The three-term congressman from El Paso broke fundraising records and became a national sensation in the fall of 2018 when he came within three points of defeating Republican Sen. Ted Cruz in Texas, a traditionally red state.
O'Rourke announced he was ending his campaign on November 1, after failing to break through the crowded field. In a Medium post, he cited that the campaign did "not have the means to move forward successfully."
Read more about Beto O'Rourke's campaign.
Dropped out: Congressman Tim Ryan of Ohio
Ryan, who represents Ohio's 13th congressional district in eastern Ohio, announced he's running for president during an April 4 appearance on "The View."
A moderate Democrat who has served in the House since 2003, Ryan is best known for his passionate advocacy on behalf of Midwesterners who have suffered from the decline in manufacturing jobs in the region.
On his campaign website, Ryan says that "failed leadership and broken promises have destroyed the middle-class, forcing our economy into crisis and pushing the American Dream out of reach."
Ryan was also one of the key leaders of an unsuccessful effort spearheaded by moderate Democrats to block Nancy Pelosi from becoming Speaker of the House after Democrats took back control of the chamber in 2018.
After failing to gain any traction in the polls or qualify for the DNC fall Democratic debates, Ryan finally quit the race on October 24.
Read more about Tim Ryan's campaign.
Dropped out: Mayor Bill De Blasio of New York City
De Blasio announced his presidential run on "Good Morning America" and with a video posted to social media.
De Blasio is best known for his ambitious progressive policy proposals aimed at reducing income inequality and increasing the amount of affordable housing in New York by taxing the city's wealthiest residents.
His gruff and often blustery approach, however, has made him highly unpopular both among New Yorkers and the Democratic primary electorate.
A Quinnipiac University poll conducted in April found he has an underwater approval rating within his own city, and a Monmouth University poll released in March found that of 12 declared and potential Democratic presidential candidates, De Blasio was the only one to receive a negative favorability rating.
De Blasio dropped out of the race on September 20 after failing to qualify for the fall debates or gain any momentum in the polls.
Read more about Bill de Blasio's campaign.
Dropped out: Senator Kirsten Gillibrand of New York
Gillibrand began her political career as a moderate, blue-dog Democrat representing a conservative district in upstate New York.
She has made a name for herself as a strong progressive voice in the US Senate, in which she has served since 2009. Gillibrand has advocated for stronger policies around addressing sexual assault in the military, lowering healthcare costs, and decreasing economic and gender inequality.
Gillibrand ran a campaign centered around women's empowerment with a focus on issues like paid family leave and reproductive rights, but failed to break out in the field or crack more than 1% to 2% in the polls.
She announced she would leave the race on August 28 after failing to qualify for the September primary debate.
Read more about Kirsten Gillibrand's campaign.
Dropped out: Congressman Seth Moulton of Massachusetts
Moulton, who has represented Massachusetts' 6th congressional district since 2015, became the 19th Democrat to join the 2020 presidential field on April 22.
"I am running because I am a patriot, because I believe in this country and because I have never wanted to sit on the sidelines when it comes to serving it,"Moulton told ABC's George Stephanopoulos.
Before running for Congress, Moulton served in the Marine Corps and completed four tours of duty in Iraq. A relatively moderate Democrat, he focused his presidential campaign on issues of foreign policy and national security.
Moulton dropped out of the race on August 23 to run for re-election in the House after he failed to qualify for any Democratic primary debates.
Read more about Seth Moulton's campaign.
Dropped out: Washington Governor Jay Inslee
Inslee, who has served as governor of Washington since 2012, has held some form of public office for most of the past 30 years. The long-time lawmaker is billing himself as the "climate candidate."
"I'm Jay Inslee and I'm running for president because I am the only candidate who will make defeating climate change our nation's number one priority," Inslee said in a video released March 1.
While governor, Inslee has made reducing carbon emissions and promoting renewable energy a top priority.
The video also shows Inslee in the aftermath of wildfires as he says in a voiceover: "We are the first generation to feel the sting of climate change. And we're the last that can do something about it."
After participating in the first two debates and putting climate change on the agenda as a crucial campaign issue, Inslee announced he would drop out of the race on August 21.
Read more about Jay Inslee's campaign.
Dropped out: former Colorado Governor John Hickenlooper
Hickenlooper launched his 2020 presidential campaign on March 4, making the former Colorado governor the 14th Democratic candidate to enter the field.
Hickenlooper, 66, was highly popular as governor for two terms before being succeeded by Democratic Gov. Jared Polis. Before that, he served as mayor of Denver (a nonpartisan position) and was a successful businessman who founded Colorado's first brewery pub, helping bring jobs and economic development to Denver.
Hickenlooper struggled to stand out as a viable centrist candidate in the shadow of Biden, however and dropped out of the presidential race on August 15, 2019.
A week later on August 22, Hickenlooper jumped into Colorado's US Senate race to challenge vulnerable GOP. Sen Cory Gardner in 2020.
Read more about John Hickenlooper's campaign.
Dropped out: former Alaska Sen. Mike Gravel
Gravel, now 89, officially filed to run for president on April 2. His leftist, anti-war presidential campaign was originally a protest campaign with the goal of simply raising enough money for Gravel to qualify for the first Democratic debates, but he's now running to win.
The Gravel campaign is running on a platform of anti-imperialist and leftist principles, and is being managed by three teenagers from New York, who are innovative-ly using Twitter to get out the former senator's message.
After failing to make any of the debates, Gravel dropped out of the race and endorsed Sanders on August 6, 2019.
Read more about Mike Gravel's campaign.
Dropped out: California Congressman Eric Swalwell
Swalwell, who has represented California's 15th Congressional district since 2013, announced the launch of his presidential campaign on "The Late Show with Stephen Colbert" on April 8.
The 18th Democrat to jump into the race, Swalwell ran a campaign largely focused on reducing gun violence in America and directly taking on the National Rifle Association, an organization he sees as directly contributing to gun violence.
Swalwell currently serves on the high-profile House Select Committee on Intelligence and the Judiciary Committee and has been actively involved in those committees' investigations into Russian interference in the 2016 election.
On July 8, Swalwell dropped out of the 2020 presidential race to run for re-election in the House after failing to break through 1% in the polls and disappointing second-quarter fundraising performance.
