WASHINGTON >> The high-dollar fundraising world is whirring to life for Vice President Kamala Harris after weeks in which Democratic donors were dejected, demoralized and utterly battered.

Since the announcement of her presidential campaign, Harris has not only raked in $130 million primarily from small donors but also gathered big check after big check from billionaires and millionaires as they stockpile money into the newly renamed Harris Victory Fund. Her fundraisers, armed with a new Harris logo, went to work.

Major fundraisers — one of whom told President Joe Biden’s campaign just days ago that he thought the campaign could count on only about 25% of its allied donors to support Biden — are now swamped with a flood of interest from donors.

Harris has no time to waste, having taken over the top of the Democratic ticket with just over 100 days to go and without the years of lead time that Biden had to cultivate major donors, soothe them and coax them to hand over their money. On Friday, Harris is scheduled to address her National Finance Committee for the first time, according to an invitation seen by The New York Times.

Harris campaign officials spent Tuesday and Wednesday energizing their supporters from Beverly Hills to the Hamptons.

On Wednesday, about 40 high-powered finance and Big Law executives joined a Zoom call organized by superlawyer Brad Karp, former New York City mayoral candidate Ray McGuire and a few others to discuss how Wall Street could best support a Harris ticket. Speakers included Rufus Gifford, the campaign’s finance chair, and donors inquired about Harris’ position on Israel, her posture on the economy and her selection of a running mate, according to two people on the call.

In Hollywood, Harris campaign officials joined calls Tuesday and Wednesday with people from across the creative and entertainment industry to talk about fundraising and organize celebrities on behalf of the Harris campaign, according to two people with knowledge of the outreach.

“Donors are calling asking, ‘How and where can I contribute to Harris for President?’” said Andy Spahn, a top fundraiser in Hollywood. He added that there was “tremendous excitement and enthusiasm for Kamala’s candidacy here.”

Farther north in California, in Silicon Valley, venture capitalists were circulating letters that they planned to publicly release in which they would announce their support for Harris, in part to combat the narrative that their industry is tilting rightward, according to two people with knowledge of the letters. Harris campaign officials in phone calls this week have asked tech leaders for help organizing their industry’s support, the people said.

Steve Spinner, who was a top Democratic fundraiser in the tech industry for Barack Obama’s campaign in 2008, said there was something that was “beautiful about Sunday and Monday” that had reminded him of that year.

“It was the first time we’ve had an Obama-like moment,” he said of Harris’ swift ascent after Biden dropped out of the race, “a feeling where it was pure and it was good, and people were doing things bigger than themselves.”

A Silicon Valley fundraising swing for the campaign is in the works, according to three people familiar with the planning. There is significant demand from within the tech industry to host one of the events, it was said.
