The first Democratic debates will take place this week — here’s everyone who has officially announced they are running for president in 2020

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.”

New York City Mayor Bill De Blasio

Montana Governor Steve Bullock

Colorado Senator Michael Bennet

Former Vice President and Delaware Senator Joe Biden

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.

Massachusetts congressman Seth Moulton

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’s focusing his presidential campaign on issues of foreign policy and national security.

Former Massachusetts Governor Bill Weld

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.”

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 is running 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.

“I see a country in quicksand,” Swalwell told Colbert of his decision to run.

“Unable to solve threats from abroad, and unable to make life better for people here at home…none of that is going to change unless we get a leader willing to go big on the issues we take on, be bold on the solutions we offer and do good in the way that we govern.”

Ohio Congressman Tim Ryan

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.

Former Alaska Sen. Mike Gravel

Miramar, Florida Mayor Wayne Messam

Messam announced his long-shot bid for the presidency on March 28, the 16th candidate, third mayor, and first person from the southeast to jump into the Democratic primary field.

“The American Dream my parents sought when they came from Jamaica with just a 5th-grade education is fleeting,” he wrote on the day of his announcement. “Together, we can put the American Dream back within reach for all.”

Messam, 44, has served as the mayor of the city of Miramar, which is located in South Florida and boasts a population of 140,000 people, since 2015.

He previously served as a city commissioner from 2011 to 2015, and founded a construction company with his wife.

Former Texas Congressman Beto O’Rourke

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.

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.

“I’m running for president because we need dreamers in Washington but we also need to get things done,” he said in his announcement video. “I’ve proven again and again I can bring people together to produce the progressive change Washington has failed to deliver.”

Read more about John Hickenlooper’s campaign.

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.”

Vermont Senator Bernie Sanders

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.

Minnesota Senator Amy Klobuchar

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.

New Jersey Senator Cory Booker

Cory Booker, the 11th Democrat to jump into the race, officially announced his candidacy for President on February 1.

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.

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.

Hawaii Representative Tulsi Gabbard

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.
