Wasn’t Kamala Harris’ candidacy “locked”? Many Democratic officials on Sunday rushed to support the vice president of the United States, who is currently considered the most likely candidate for the party’s nomination for the presidency of the United States in November after President Joe Biden withdrew from the race, but some of the most important figures of the faction, especially the former president Barack Obama and the former president of the House of Representatives Nancy Pelosi, have not been expressed.

After weeks of infighting within Democratic ranks over whether or not Mr. Biden, 81, should remain on the campaign trail, it is critical for Ms. Harris to rally the party behind her with less than 100 days to go until the polls open.

But there are plenty of doubts in the Democratic party about whether and to what extent Kamala Harris Can Beat Former President Trump. Some faction officials are suggesting that a mini-process be organized to select the strongest candidate ahead of the August convention in Chicago.

Outgoing President Biden himself came out in support of Ms. Harris yesterday, in a separate statement, following the release of his explosive letter announcing his abandonment of the effort. He was followed, almost immediately, by the powerful group of African-American congressmen, several key donors, caucuses and super PACs (“political action groups”), among them Priorities USA and Unite the Country.

“I want to offer my full support and approval to Kamala so that she is our party’s candidate this year. Democrats — it’s time to unite and defeat Trump. Let’s do it,” Mr. Biden said via X yesterday.

The list of Democrats continued to grow as the day wore on. As of last night, she had been endorsed by California Governor Gavin Newsom, Colorado Governor Jared Polis, North Carolina Governor Roy Cooper, Pennsylvania Governor Josh Sapiro, Arizona Sen. Mark Kelly, Washington Senator Patti Marie, South Carolina Congressman James Clyburn, Congresswoman Pramila Jayapal…

An adviser to Reed Hoffman, the founder of LinkedIn and a major Democratic donor, called Ms. Harris the “personification of the American dream,” recalling that she is a child of immigrants, and “the personification of toughness” as she served as California’s top prosecutor.

All 50 state Democratic leaders have announced their support for Kamala Harris. Likewise the Democratic delegates to the convention from the states of Tennessee, Louisiana, South Carolina and North Carolina.

Former President Bill Clinton and Hillary Clinton, Barack Obama’s former first lady and secretary of state, also endorsed the vice president. However, forms of the lineup like Mr. Obama and Mrs. Pelosirefrained from endorsing Ms. Harris, or any other candidate.

A source briefed on his intentions said the former president will seek to unify the party after the candidate is named.

Senate Majority Leader Chuck Schumer, who praised President Biden’s decision to step aside, also chose not to comment.

Sen. Peter Wells, the first Democratic senator to publicly call on the president to quit, has called for an “open” convention, meaning that delegates should be allowed to choose the nominee.

A Democratic donor said he would support a ballot with Ms. Harris and Pennsylvania Gov. Sapiro as his vice-presidential candidate if Democrats were to win the contested state.

It is not clear at this stage who would Kamala Harris pick as her running mate if she did secure the nomination.

Also, a grassroots organization that had backed former Republican nominee Nikki Haley and supported President Biden under the name “Haley Voters for Biden” changed its name yesterday to “Haley Voters for Harris.”
