Withdrawal of Joe Biden from the 2024 United States presidential election

On July 21, 2024, Joe Biden, the 46th president of the United States, announced his withdrawal from the 2024 United States presidential election.

Biden, a Democrat who had been elected president in 2020, stated on April 25, 2023, that he would run for re-election in 2024 with incumbent Vice President Kamala Harris as his running mate. Biden went on to win an overwhelming majority of delegates in the 2024 Democratic Party presidential primaries, where he easily defeated challengers such as Representative Dean Phillips and became the party's presumptive nominee.

Concerns about Biden's age and health had emerged during his presidency. These concerns increased following the June 2024 presidential debate between Biden and Republican Party candidate Donald Trump. Biden's debate performance was widely criticized; he lost his train of thought, had a faltering appearance, spoke with a hoarse voice, and failed to recall statistics or coherently express his opinion on several occasions. While he insisted that he would continue his campaign, Biden subsequently faced calls from fellow Democrats and from the editorial boards of major news outlets to withdraw from the race. By July 19, 2024, more than 30 senior Democrats had called for his withdrawal.

Biden ultimately ended his re-election campaign on July 21, 2024, before being officially re-nominated at the Democratic National Convention, becoming the first incumbent president to end a re-election campaign before Election Day since Lyndon B. Johnson in 1968. After adding that he would continue serving as president for the remainder of his term, Biden immediately endorsed Harris to replace him in his place as the party's presidential nominee. Harris officially became the party's presidential nominee and went on to lose the 2024 election to Trump.
