The 2020 Democratic presidential nomination was a key event in the United States' electoral process, where candidates competed to become the Democratic Party's nominee for the presidential election. Major candidates included Joe Biden, Bernie Sanders, and Elizabeth Warren, among others. The primaries began in early 2020, with Iowa and New Hampshire holding the first contests. Joe Biden emerged as the frontrunner after a strong performance in the South Carolina primary, leading to a series of endorsements and victories on Super Tuesday. Ultimately, he secured the nomination, positioning himself against the incumbent president, Donald Trump, in the November 2020 election.
