Harris looks to lock up Democratic nomination after Biden steps aside, reordering 2024 race

U.S. Vice President Kamala Harris moved swiftly to lock up Democratic delegates behind her campaign for the White House after President Joe Biden stepped aside amid concerns from within their own party that he would be unable to defeat Donald Trump.

U.S. Vice President Kamala Harris moved swiftly to lock up Democratic delegates behind her campaign for the White House after President Joe Biden stepped aside amid concerns from within their own party that he would be unable to defeat Donald Trump.

Biden's exit Sunday, prompted by Democratic worries over his fitness for office, was a seismic shift to the presidential contest that upended both parties' carefully honed plans for the race.

Aiming to put weeks of intraparty drama over Biden's candidacy behind them, prominent Democratic elected officials, party leaders and political organizations quickly lined up behind Harris in the hours after Biden announced he was dropping his re-election campaign.

Biden's departure frees up his delegates to vote for whomever they choose. Harris, whom Biden backed after ending his candidacy, is thus far the only declared candidate and was working to quickly secure endorsements from a majority of delegates.

It's only the first item on a staggering political to-do list for her after Biden's decision to exit the race, which she learned of on a Sunday morning call with the president. If she's successful at locking up the nomination, she must also pick a running mate and pivot a massive political operation to boost her candidacy instead of Biden's with just over 100 days until Election Day.

On Sunday afternoon, Biden's campaign formally changed its name to Harris for President, reflecting that she is inheriting his political operation of more than 1,000 staffers and a war chest that stood at nearly $96 million at the end of June.

Harris spent much of Sunday surrounded by family and staff, making more than 100 calls to Democratic officials to line up their support for her candidacy, according to a person familiar with the matter who spoke on the condition of anonymity to discuss the effort. It comes as she tries to move her party past the painful, public wrangling that had defined the weeks since the Biden's disastrous June 27 debate with Trump.
