“This campaign is Scranton versus Palm Beach,” Biden said in a video posted to X.

“Folks, you know Trump is down in Florida today raising money from a bunch of hedge fund billionaires who want him to cut Social Security and Medicare and their taxes,” he claimed in the 54-second clip.

Trump’s swanky soiree, hosted by hedge funder John Paulson at his $110 million Palm Beach mansion, attracted a host of prominent Republicans who paid between $250,000 and $814,000 for entry.

Biden then touted his campaign’s March fundraising report, released earlier Saturday, which tallied a $90 million intake for the month — boosted, he said, by an influx of small-dollar donations under $200.

“Our campaign now has 1.6 million individual donors, and more than half a million of those donors are brand-new since 2020,” Biden boasted.

He did not mention the $500,000 top ticket price of his lavish New York City fundraiser last week, which raised more than $25 million and featured appearances by former presidents Barack Obama and Bill Clinton, plus performances by Lizzo, Queen Latifah, and others.

Biden’s new small-dollar totals, if confirmed, would represent a sharp turnaround for the two candidates.

Trump and his GOP committees took in a record $626.6 million from grassroots givers in 2020, far outpacing Biden in the category.
