Who's running for president? Meet the 2020 Democrats who are in (and out) of the race

Entered race: May 2, 2019

Dropped out: Feb. 11, 2020 after the New Hampshire primaries

Age: 54

Education: B.A., Wesleyan University; J.D., Yale Law School

Veteran: No

Best known for: A scorching speech slamming Republican Sen. Ted Cruz of Texas during the recent government shutdown, then publicly announcing that he had prostate cancer in March.

Strength: Bennet is viewed as a wonky, issue-oriented pragmatist who has won tough campaigns, which could be a winning combination for Democratic voters who don't want to veer too far left but are eager to beat Trump.

Weakness: Bennet is not as well known as many other senators competing for the Democratic nomination and has no natural base.

Entered race: March 19, 2019

Dropped out: July 31, 2019

Age: 89

Education: B.S., Columbia University

Veteran: Yes

Best known for: Serving as U.S. senator representing Alaska from 1969 to 1981 who read the Pentagon Papers into the congressional record. He also ran for president unsuccessfully in 2008, first as a Democrat and then as a Libertarian.

Biggest strength: Long antiwar record, which could play well with the progressive wing of the party.

Biggest weakness: Oldest candidate in the race by far. Gravel's campaign has previously said he wanted to make the debate stage in an effort to push the party to the left, not to win.
