Vice President Kamala Harris, a daughter of immigrants who rose through the California political and law enforcement ranks to become the first female vice president in U.S. history, has secured the Democratic presidential nomination. More than four years after her first attempt at the presidency collapsed, Harris’ coronation as her party’s standard-bearer will cap a tumultuous and frenetic period for Democrats prompted by President Joe Biden’s disastrous June debate performance that shattered his own supporters’ confidence in his reelection prospects and spurred extraordinary intraparty warfare about whether he should stay in the race. Just as soon as Biden abruptly ended his candidacy, Harris and her team worked rapidly to secure backing from the 1,976 party delegates needed to clinch the nomination in a formal roll call vote. She reached that marker at warp speed, with an Associated Press survey of delegates nationwide showing she locked down the necessary commitments a mere 32 hours after Biden’s announcement. Harris' nomination became official after a five-day round of online balloting by Democratic National Convention delegates that ended Monday night. The party had long contemplated the early virtual roll call to ensure Biden would appear on the ballot in every state.
