36 people who could challenge Trump in 2020

The field of Democrats who could jockey for a White House bid in 2020 is growing by the day, as more and more potential candidates are eyed as possible challengers to President TrumpDonald John TrumpKoch-backed group launches six-figure ad buy against Heitkamp Anti-abortion Dem wins primary fight Lipinski holds slim lead in tough Illinois primary fight MORE.

Many potential candidates have sought to stand out from the field through vocal opposition to the Trump agenda — voting against the bipartisan two-year budget deal or calling for the president’s resignation.

Here are 36 potential candidates, from top contenders to long shots, who could run in 2020:

Sen. Bernie SandersBernard (Bernie) SandersAnti-abortion Dem wins primary fight Lipinski holds slim lead in tough Illinois primary fight Overnight Defense: Senate sides with Trump on military role in Yemen | Dem vets push for new war authorization on Iraq anniversary | General says time isn't 'right' for space corps MORE (I-Vt.)
Sanders reportedly met with top advisers in late January to discuss a potential 2020 run. But Sanders said he’s focused on his reelection in 2018. Still, the 2016 Democratic primary candidate hasn’t shied away from opportunities to contrast himself to Trump. The favorite of the Democrats’ progressive wing delivered his own response to the State of the Union address, calling Trump a “bully.” If elected, Sanders would be 79 when taking office in 2021.
Former Vice President Joe BidenJoseph (Joe) Robinette BidenKentucky candidate takes heat for tweeting he'd like to use congressman for target practice The Hill's 12:30 Report Biden hosting fundraiser in Miami MORE
A recent poll of the hypothetical 2020 field showed Biden, who benefits from massive name recognition after two terms as vice president, easily leading the Democratic pack. Biden reportedly said privately that he believes he’s the only Democrat who can beat Trump in 2020. And Biden, who would be 78 in January 2021, publicly weighed the possibility of running on ABC’s “The View” in December.
Sen. Kirsten GillibrandKirsten Elizabeth GillibrandGillibrand endorses Cuomo for reelection Coalition presses Transportation Dept. for stricter oversight of driverless cars Do Dems need someone people like to beat Trump? MORE (D-N.Y.)
Gillibrand, 51, gained prominence for speaking out against sexual harassment and assault, and has sought to position herself as one of Trump’s leading Senate antagonists by frequently voting against his nominees. After Trump tweeted that she “would do anything” for campaign donations — which many thought had sexual implications — Gillibrand shot back that Trump “cannot silence me” with a “sexist smear.”
Sen. Elizabeth WarrenElizabeth Ann WarrenMichael Moore: Russia, Stormy Daniels stories are 'shiny keys to distract us' Fix the flaw in financial self-regulation Power struggle threatens to sink bank legislation MORE (D-Mass.)
Warren, another progressive favorite, is frequently touted as a top 2020 contender. But she’s downplayed presidential rumors and says she’s focused on her reelection in 2018. Warren, who will be 71 on Inauguration Day in 2021, was one of several Senate Democrats with possible presidential ambitions who voted against the two-year budget deal. Warren hasn’t gone as far as some colleagues, however, who have called for Trump to resign because of the sexual harassment allegations against him.
Sen. Cory BookerCory Anthony BookerBooker: 'This is the most important midterm election of our lifetime' Senate GOP: Legislation to protect Mueller not needed NY and NJ lawmakers press Ryan on Gateway project funding MORE (D-N.J.)

Sen. Kamala HarrisKamala Devi HarrisSupreme Court must agree with California and end lies spread by fake women's health centers Senate confirms Trump's border chief Do Dems need someone people like to beat Trump? MORE (D-Calif.)
Harris, 53, a rising star in the party, generated national attention after she was cut off from questioning a witness at Senate Intelligence Committee hearings. But Harris, like many potential 2020 candidates, has insisted that she’s not thinking about future campaigns.
Former talk show host Oprah Winfrey
Winfrey set off presidential rumors after her speech about sexual harassment at the Golden Globes last month. But Winfrey, 64, told InStyle Magazine that she doesn’t “have the DNA for it.”

Holder is the latest politician who wouldn’t rule out a 2020 bid. When asked about a future White House run, he responded, “We’ll see.” Holder, 67, said he’s focused on his National Democratic Redistricting Committee, a Democratic effort to reverse Republican redistricting gains.

Delaney, 54, became the first declared presidential candidate of 2020 when he launched his campaign last July. The retiring congressman commissioned the first ad of the 2020 primaries in Iowa — which holds the first presidential caucuses.

Rep. Luis Gutiérrez (D-Ill.)
Gutiérrez, 62, is also retiring from Congress at the end of 2018, and is reportedly exploring a presidential run. The longtime congressman is a strong proponent of immigration reform, and backed an effort to introduce articles of impeachment against Trump.
Billionaire mega-donor Tom Steyer
Steyer, 60, ruled out running for office in 2018, but he hasn’t closed the door on 2020. He plans to spend $30 million to help Democrats take back the House in 2018, and is continuing his ad campaign calling for Trump’s impeachment.

Former Missouri Secretary of State Jason Kander
After losing a surprisingly close Missouri Senate race in 2016, 36-year-old Kander has raised his national profile with a new national group meant to fight voter suppression. He’s also made the rounds at various local Democratic events, making stops in key early states.

South Bend, Ind., Mayor Pete Buttigieg (D)
Buttigieg, 36, has kept busy since making a headline-grabbing bid to chair the DNC. The openly gay Navy reservist has traveled the country to speak on panels and headline local Democratic Party events, and would offer Democrats a chance to field a midwestern politician — although he could be criticized for a lack of experience beyond the local level.

New York City Mayor Bill de Blasio (D)
Fresh off his reelection as mayor, the 56-year-old de Blasio stoked speculation about a bid with his trip to Iowa late last year. While he said that he isn’t running for president, he’s kept up rumors of a possible bid while emerging as a progressive Trump critic.

Sen. Sherrod BrownSherrod Campbell BrownDemocratic senator: People don’t know what’s going on between Trump and Putin Power struggle threatens to sink bank legislation Pension committee must deliver on retirement promise MORE (D-Ohio)
Brown is a familiar name in White House shortlists, and was considered for Clinton’s vice president pick. But Brown, 65, could face a tough reelection race this cycle in one of the 10 states that Trump won in 2016.

Dallas Mavericks owner Mark Cuban
The 59-year-old billionaire businessman and “Shark Tank” star said late last year that there’s a “10 percent” chance he runs in 2020.
