History was made on July 21 when President Joe Biden announced his withdrawal from the 2024 presidential race.
Biden is the first sitting president since Lyndon B. Johnson announced in 1968 that he would not seek re-election, when Johnson dropped out after a poor showing in the New Hampshire Democratic primary, and the first individual in presidential history to decline to run after winning the primary; Biden won nearly 90% of the delegates in the 2024 primary.
