It took Vice President Kamala Harris less than 24 hours to launch a “Harris for President” campaign and start swinging at perennial Republican nominee and former President Donald Trump, all while Democratic heavy weights continued to line up behind her candidacy.

The first message labeled as from the “Harris for President” campaign hit inboxes early Monday, arriving shortly after midnight and containing a lengthy list of Democratic lawmakers that are publicly backing the Vice President’s nomination to the top of the party ticket following the Sunday afternoon announcement by President Joe Biden that he will not seek a second term.

The message, delivered from the “joebiden.com” web domain used by the now-defunct Biden-Harris 2024 campaign, declared that “hundreds of elected officials from across the political spectrum followed President Biden’s lead and announced their full-throated support for Vice President Harris as the Democratic nominee for president to defeat Donald Trump in November.”

“As Vice President Harris said, she ‘will do everything in [her] power to unite the Democratic Party—and unite our nation—to defeat Donald Trump and his extreme Project 2025 agenda,’” the Harris campaign wrote.

Later, the campaign shared a long list of liberal leaning organizations which had also jumped on board, including the American Federation of Teachers, EMILY’s List, the SEIU, and the United Farm Workers.

“Vice President Harris will have the organizing force of the entire backbone of the Democratic Party behind her as she campaigns to defeat Trump,” her campaign declared.

Republicans, the newly-minted Harris campaign claims, are terrified of a Harris vs. Trump general election match-up. Harris, California’s former Attorney General, is used to dealing with felons like the former President, Harris for President Spokesperson Ammar Moussa said in a statement.

“Vice President Kamala Harris has held criminals accountable her entire career – and Donald Trump will be no different. Vice President Harris has dedicated her career to making life better for working people – while Trump only cares about himself. That’s the contrast the American people will see over the next 106 days,” Moussa said.

Massachusetts Gov. Maura Healey, who stopped short of endorsing Harris on Sunday, joined the chorus of voices coming out in full force behind the Vice President in a statement shared by her campaign the very next day.

“The future of our country as we know it is on the line. That’s why I am thrilled to support Kamala Harris as she works to earn the Democratic nomination and beat Donald Trump,” Healey said.

Healey’s endorsement came on top of declarations of support from Illinois Gov. J.B. Pritzker, Kentucky Gov. Andy Beshear, Michigan’s Gov. Gretchen Whitmer, and Pennsylvania Gov. Josh Shapiro, all of whom were rumored to possess presidential aspirations of their own.

Former House Speaker Nancy Pelosi, still a powerhouse in the party and part of the push for Biden to step aside, also endorsed Harris.

Trump, meanwhile, was “watching the Fake News” on Monday and apparently seeing coverage which led him to declare Harris is “dumb as a rock” and “a totally failed and insignificant Vice President” that the Democratic Party is attempting to make “into a future ‘great’ President.”

“No, it just doesn’t work that way,” he wrote on his Truth Social Media platform.
