More than two dozen Democrats launched presidential campaigns in 2019 — but just 15 remain in the race as the year comes to a close.
The race for the Democratic nomination has so far been marked by a fight between centrist candidates and those from the progressive camp over who is best suited to take on President Trump in 2020.
As Democrats across the country prepare to cast votes in primaries in 2020, here’s a look back at some of the year’s key moments of the early stages of the primary race:
Former Vice President Joe Biden
April 25: Officially enters crowded race, becoming an instant front-runner after skipping the 2016 race.
June 27: Comes under attack from Sen. Kamala Harris (D-Calif.) during the second night of the first primary debate over his stance on racial busing.

Feb. 19: Launches second race for the Democratic nomination after an unexpectedly strong, but unsuccessful, challenge against 2016 nominee Hillary Clinton.

Rep. Tulsi Gabbard (D-Hawaii)
Jan. 11: Officially launches her campaign, focusing on her foreign policy experience as a military combat veteran.
