In a significant turn of events, Kamala Harris, the Democratic vice-presidential nominee, has taken over Joe Biden's political operation after winning the party's nomination. Harris, who learned about Biden's decision to exit the race during a Sunday morning call with the former vice president, now faces a long list of tasks as she prepares for the upcoming election.

One of Harris' immediate priorities is selecting a running mate to join her on the ticket. Additionally, she needs to redirect the substantial political operation that she has inherited from Biden, which includes more than 1,000 staff members and a sizable war chest of nearly $96 million as of June's end.

The campaign wasted no time in rallying support and raising funds, as Harris managed to raise an impressive $49.6 million in donations within the first 15 hours after Biden's endorsement, according to campaign spokesperson Lauren Hitt.

Amidst this transition, Harris spent Sunday reaching out to over 100 Democratic officials to secure their support for her candidacy. Her aim is to move past the recent public divisions within the party and create a united front leading up to the election.

Notably, Harris garnered swift endorsements from influential caucuses and political organizations, including the AAPI Victory Fund, The Collective PAC, the Latino Victory Fund, as well as the chairs of the Congressional Progressive Caucus, Congressional Hispanic Caucus, and the entire Congressional Black Caucus. This level of support indicates that the Democratic Party is coalescing behind Harris as the nominee.

Even several prominent male figures who were previously mentioned as potential running mates for Harris, such as Pennsylvania Governor Josh Shapiro, North Carolina Governor Roy Cooper, and Arizona Senator Mark Kelly, promptly showed their support by endorsing her candidacy.

However, former President Barack Obama has decided to hold off on an immediate endorsement, expressing concerns that a quick transition to Harris might be seen as a coronation. Instead, Obama has pledged his support to the eventual party nominee.

Additionally, West Virginia Senator Joe Manchin, who had considered re-registering as a Democrat to compete against Biden for the nomination, confirmed that he will not run as a candidate.

Harris's first public appearance since becoming the Democratic nominee was scheduled for Monday at the White House, where she would speak at an event honoring NCAA championship teams. This event showcases her need to balance her current role as a senator with her new responsibility as a candidate.

Acknowledging Biden's endorsement, Harris expressed her gratitude but emphasized her determination to earn the nomination in her own right. She pledged to unite the Democratic Party and the nation to defeat President Donald Trump and his proposed Project 2025 agenda.

Biden, on the other hand, plans to address the nation later this week to discuss his decision to step aside and focus solely on fulfilling his presidential duties. In his statement, he wrote that he believes it is in the best interest of his party and the country to support Harris as the nominee.

The Democratic National Convention, originally scheduled for August 19-22 in Chicago, will now adapt its nomination process to reflect Biden's exit. The party's rules committee is set to meet this week to finalize the adjustments.

Congressional Hispanic Caucus chairwoman Nanette Barragan, showing her full support for Biden, spoke with Harris and conveyed her willingness to follow a nomination process that adheres to regular order rather than opting for a virtual roll call.

Democratic National Committee Chair Jaime Harrison assured the party's commitment to a transparent and orderly process in selecting a candidate capable of defeating Donald Trump in November.

With Harris now at the helm, the Democratic Party is gearing up for a united front as they face the upcoming election against President Trump and his Republican party.
