Kamala Harris Fundraising Effort Nets $2 Million in 24 Hours After Debate

WASHINGTON — Senator Kamala Harris of California raised $2 million in the first 24 hours following the start of Thursday’s presidential primary debate, a total that suggests her performance resonated with many Democratic donors.

Ms. Harris, whose preplanned sparring with former Vice President Joseph R. Biden Jr. over his record on race relations was the highlight of two nights of debates, collected donations from 63,277 people, according to a campaign aide. The aide said 58 percent of those donors had not contributed to her campaign before.

The haul comes at a key moment for Ms. Harris. Sunday marks the end of the year’s second fund-raising quarter, a marker by which the 24 Democrats running for president will be judged.

It also virtually ensures she will meet threshold set by the Democratic National Committee to participate in debates throughout the fall and winter.

Ms. Harris and other presidential candidates are required to report their fund-raising figures to the Federal Election Commission by July 15, though many are expected to release their totals as soon as Monday morning. Mr. Biden and Mayor Pete Buttigieg of South Bend, Ind., are expected to post large fundraising numbers for the second quarter of 2019.
