With former vice president Joe Biden entering the 2020 Democratic presidential contest on Thursday, the field is largely set, with all the big names included.
The sprawling Democratic field features candidates ranging from 37 to 77 years old; liberals and moderates; senators, governors and mayors; and an unprecedented number of women and minorities.
Democrats view the upcoming election as a must-win, and they are looking to nominate someone who is their best hope to beat President Donald Trump who stunned the party by beating Hillary Clinton in 2016.
Here are the 20 candidates:
Best known for: Being former President Barack Obama’s vice president from 2009 to 2017 and US senator from Delaware from 1973 to 2009.
Biggest strength: He is well-known nationally and popular in some places Democrats have lost recently, such as working-class swing states Wisconsin, Michigan and Pennsylvania, his birthplace.
The core values of this nationâ¦ our standing in the worldâ¦ our very democracy...everything that has made America -- America --is at stake. Thatâs why today Iâm announcing my candidacy for President of the United States. #Joe2020 https://t.co/jzaQbyTEz3— Joe Biden (@JoeBiden) April 25, 2019
Biggest weakness: Mr Biden would be the oldest person ever elected president, with a nearly five-decade record for opponents to comb through, at a time many in his party are clamouring for a new generation to take the reins.
The notoriously chatty former senator also tends to commit verbal gaffes and faced recent accusations by some women of uninvited, though nonsexual, touching.
Best known for: Serving as mayor of Newark and, currently, US senator from New Jersey. He made headlines last year during his self-proclaimed “‘I am Spartacus’ moment” as he flouted Senate rules against disclosing confidential documents during Brett Kavanaugh’s Supreme Court confirmation fight.
Biggest strength: His optimistic, unity-first attitude could resonate at a time of deep political divisions.
Biggest weakness: Trying to convince voters that he is tough enough to take on Mr Trump.
Best known for: Serving as mayor of South Bend, Indiana, and being a former Naval intelligence officer.
Biggest strength: He has won over voters and many sceptics with his intelligence and an articulate yet plain-spoken speaking style. He has also shown an ability to inspire voters of different ages with a message of hope and “a new generation of leadership” and has been able to raise millions more than many of his Democratic rivals.
Biggest weakness: His youth and lack of political experience, his only public office has been leading the community of about 100,000 people, will give some voters pause. He also will need to ramp up his campaign operations and do more to appeal to minority voters in order to maintain his early momentum.
Best Known for: Serving as Health and Human Services secretary during President Barack Obama’s second term and as the mayor of San Antonio, Texas, for five years.
Biggest strength: His youthfulness and status as the only Latino in the race could help him win the votes of Democrats looking for a new face of their party.

Last night at #NIOSA (Night in Old San Antonio) I got to see old friends, meet new ones, and hand out some of my new Fiesta medals!
We still have some available â¡ï¸ https://t.co/9Xh4V0OlWq #vivafiesta #satx pic.twitter.com/86WBfWI1dS
Biggest weakness: His fundraising lags well behind other contenders.
Best known for: Being a former congressman from Maryland.
Biggest strength: He has rolled out a rural-focus policy that includes proposals to strengthen family farmers and rural infrastructure, a plan that could play well in the battleground Rust Belt states won by Mr Trump.
The President clearly cares more about his Twitter followers than the American people. His continued dishonesty and weaponization of social media has been divisive. I am calling on all Americans to #UnfollowTrump and hit him where it actually hurts him... his ego. pic.twitter.com/Z6cNfNckUU— John Delaney (@JohnDelaney) April 24, 2019
Biggest weakness: Low name recognition.
Best known for: Serving as a US representative for Hawaii; the first American Samoan and first Hindu to be elected to Congress.
Biggest strength: Her military service in Iraq and Kuwait with the Hawaii National Guard.

Biggest weakness: She has been criticised for travelling to Syria in 2017 to meet with Syrian President Bashar Assad, who has been accused of war crimes and even genocide. She was also forced to apologise for her past work advocating against gay rights.
Best known for: The senator from New York is one of her chamber’s most vocal members on issues of sexual harassment, military sexual assault, equal pay for women and family leave.
Biggest strength: Not being afraid to defy her own party in the #MeToo era, calling early for Democratic Senator Al Franken’s resignation over sexual misconduct allegations and saying Bill Clinton should have voluntary left the presidency over an affair with intern Monica Lewinsky.
I've always been an underdog. I'm used to it. I've also won every race I've run. So when I say I'm not worried about being discounted now, you can believe it. pic.twitter.com/iLh51neXiT— Kirsten Gillibrand (@SenGillibrand) April 25, 2019
Biggest weakness: Sluggish campaign fundraising in the wake of some unpleasant #MeToo headlines of her own, with Ms Gillibrand acknowledging there were “post-investigation human errors” made when her Senate office investigated allegations of sexual misconduct against various staffers.
Best known for: The former California attorney general is now the junior US senator from California, known for her rigorous questioning of Mr Trump’s nominees.
Biggest strength: As the one black woman in the race, she has able to tap into networks like historically black colleges and universities and her Alpha Kappa Alpha sorority that have not been fully realised before.
Some will say my plan to combat gun violence is âtoo bold.â As president, if Congress continues to bury its head in the sand, I will act. Too many people have died for us to wait any longer. https://t.co/KJEMAZ72az— Kamala Harris (@KamalaHarris) April 25, 2019
Biggest weakness: Her prosecutorial record has come under scrutiny amid a push for criminal justice reform.
Best known for: Being a quirky brewpub owner who became a politician late in life, rising to governor of Colorado.
Biggest strength: An unorthodox political persona and successful electoral track record in a swing state. He is one of the few governors in a race heavy with senators and DC stalwarts.
Today, this amazing group shared with me the hardship of full-time pay that's below a living wage. In America, weâre subjecting those who arenât born into opportunity to a system that is rigged against them, no matter how hard they work. We can -and will- do better. #cliffeffect pic.twitter.com/VebrGYVL7U— John Hickenlooper (@Hickenlooper) April 24, 2019
Biggest weakness: He has previously joked that he was too centrist to win the Democratic nomination. As governor he disappointed some environmentalists by not regulating the energy industry more. He’s another white male baby boomer in a party filled with younger and more diverse candidates that better reflect its base.
Best known for: Being governor of Washington state and a former congressman.
Biggest strength: His campaign emphasis is on combating climate change, which he frames as an economic opportunity in addition to a moral imperative.
We know that if we have a president who will inspire the nation to a clean energy future, jobs are going to be all over the United States. I intend to be that president.— Jay Inslee (@JayInslee) April 24, 2019
Biggest weakness: He risks being labelled a one-issue candidate.
Best known for: The three-term Minnesota senator raised her national profile during a Senate committee hearing for Supreme Court nominee Brett Kavanaugh when she asked him whether he had ever had so much to drink that he did not remember what happened. He replied, “Have you?”
Biggest strength: She is known as a pragmatic politician willing to work with Republicans to get things done, a quality that has helped her win across Minnesota, including in rural areas that supported Mr Trump in 2016. She says her Midwestern sensibilities would help Democrats reclaim critical battlegrounds like Wisconsin and Michigan.
Sat down with leaders from across the country at the African American Mayors Association Annual Conference today. We talked about how we can make sure everybody in every city and town across this country has the chance to get ahead. pic.twitter.com/9OrftJ5dgH— Amy Klobuchar (@amyklobuchar) April 24, 2019
Biggest weakness: Her pragmatism may work against her in a primary, as Democratic voters increasingly embrace more liberal policies and positions. There have also been news reports that she has mistreated staff.
Best known for: Serving as the mayor of Miramar, Florida, and playing on the Florida State University Seminoles’ 1993 national championship football team.
Biggest strength: He touts his mayoral experience balancing government regulations needed to protect the environment while allowing room for companies to prosper.
The American Dream my parents sought when they came from Jamaica with just a 5th grade education is fleeting. Together, we can put the American Dream back within reach for all #ChangeCantWait pic.twitter.com/oHwrBsx5uH— Wayne Messam (@WayneMessam) March 28, 2019
Biggest weakness: Low name recognition and funding.
Best known for: The Massachusetts congressman and Iraq War veteran gained national attention for helping lead an effort within the party to reject Nancy Pelosi as House speaker after Democrats regained control of the chamber.
This is exactly why we need a Commander in Chief who understands what combat actually means instead of this "stable genius" threatening armed conflict with our third-biggest trading partner. https://t.co/j8fHzLsw7r— Seth Moulton (@sethmoulton) April 25, 2019
Biggest strength: Military and congressional experience.
Biggest weakness: Low name recognition, late start on the fundraising necessary to qualify for the summer debate stage.
Best known for: The former congressman narrowly lost the 2018 Senate race to Republican Ted Cruz in Texas, the country’s largest conservative state.
Biggest strength: A do-it-yourself campaign style that packs lots of travel and multiple events into long days and encourages off-the-cuff discussions with voters that still allow Mr O’Rourke to talk up his days as a onetime punk rock guitarist and his love for his home on the US-Mexico border.
Biggest weakness: He is longer on enthusiasm and vague, bipartisan optimism than actual policy ideas, and the style-over-substance approach could see Mr O’Rourke’s strong early fundraising slip once the curiosity begins to fade.
Best known for: The Ohio congressman made an unsuccessful bid to replace Nancy Pelosi as House Democratic leader in 2016.
Biggest strength: Mr Ryan has touted himself as a candidate who can bridge Democrats’ progressive and working-class wings to win the White House.
Biggest weakness: Low name recognition, late start on grassroots fundraising.
Best known for: A 2016 presidential primary campaign against Hillary Clinton that laid the groundwork for the leftward lurch that has dominated Democratic politics in the Trump era.
Biggest strength: The Vermont senator, who identifies himself as a democratic socialist, generated progressive energy that fuelled his insurgent 2016 campaign and the best fundraising numbers of any Democrat so far.
Today is #EarthDay. Unless we take bold action to reverse climate change, future generations will look back and ask a very simple question: "Where were they? Why didnât the United States of America lead on preventing the devastating damage that scientists were sure would come?"— Bernie Sanders (@SenSanders) April 22, 2019
Biggest weakness: Expanding his appeal beyond his largely white base of supporters.
Best known for: The California congressman is a frequent guest on cable news criticising President Donald Trump.
Biggest strength: Media savvy and youthfulness could appeal to young voters.

We started our campaign with the Parkland community because ending gun violence will be my number ONE priority as President. #EnoughIsEnough
Letâs make gun deaths obsolete: https://t.co/FgC3uOQiiE pic.twitter.com/dA8c3tted2
Biggest weakness: Low name recognition, late start on grassroots fundraising.
Best known for: The senator from Massachusetts and former Harvard University law professor whose calls for greater consumer protections led to the creation of the Consumer Financial Protection Bureau under then-President Barack Obama.
Biggest strength: Ms Warren has presented a plethora of progressive policy ideas, including eliminating existing student loan debt for millions of Americans, breaking up farming monopolies and mammoth technology firms, implementing a “wealth tax” on households with high net worth and providing universal child care.
In Iowa, I met family farmers who are getting squeezed by decades of policies that favor giant agribusinesses like Bayer-Monsanto. Time for better policy choicesâ.

Biggest weakness: She is viewed as one of the most liberal candidates in the Democratic field, which could hurt her chances among moderates. Her policy-heavy approach also risks alienating voters at a time when other candidates are appealing to hearts as much as to minds.
Best known for: Best-selling author and spiritual leader.
Biggest strength: Outsider who could draw interest from voters who are fans of her books.
Biggest weakness: Low name recognition, little political experience.
Best known for: Entrepreneur who has generated buzz with his signature proposal for universal basic income to give every American 1,000 US dollars a month, no strings attached.
Biggest strength: Robust policy agenda, tech savvy.
