Who became the Democratic nominee for president after Joe Biden dropped out of the 2024 race?

Following President Joe Biden's decision to withdraw from the 2024 presidential race on July 21, 2024, Vice President Kamala Harris became the Democratic Party's nominee for president. Biden announced his withdrawal and immediately endorsed Harris to take his place on the ticket. This move came after growing concerns regarding Biden's age and fitness for a second term, particularly following a presidential debate in late June 2024. Harris officially secured the nomination on August 5, 2024, after a virtual roll call vote. She subsequently chose Minnesota Governor Tim Walz as her running mate.

As the sitting Vice President, Kamala Harris was the most immediate and logical successor to President Biden within the Democratic Party. When a presidential nominee withdraws, the party's rules dictate the process for selecting a replacement. For the Democratic Party, the Democratic National Committee (DNC) is empowered to choose a new nominee, typically through a special meeting and majority vote. Given her position and the outgoing president's endorsement, Harris quickly consolidated support among delegates and party leaders, making her ascent to the nomination swift and decisive.

The Vice President holds a unique position, standing first in the line of presidential succession and serving as a key figure in the executive branch. Historically, the role has evolved from primarily legislative duties to a more active executive function, with vice presidents often playing significant roles in administration policy and representing the president domestically and abroad. While a presidential nominee's withdrawal is rare, the established framework for party nominations and the inherent leadership role of the Vice President ensured a clear path for Kamala Harris to step in as the Democratic standard-bearer for the 2024 election.
