Former Vice President Joe Biden, who leads most polls of Democratic president candidates, has raised a huge $21.5 million for his campaign since launching his candidacy in April.

But he trails North Bend Mayor Pete Buttigieg, who was virtually unknown on the national stage before launching his candidacy earlier in the year, whose campaign raised $24.8 million in the second quarter.

Biden, who launched his candidacy three weeks after Buttigieg, raised 436,000 donations from 256,000 donors, with the average donation around $49.

In an email to supporters, Biden's campaign said it "raised more per day than any other presidential campaign."

The news of Biden's fundraising follows a torrid week for the former VP. In a lackluster performance in the first Democratic primary debate last Thursday was confronted by Sen. Kamala Harris about his warm relationship with segregationist senators.

Harris' questioning saw Biden's support dip among African Americans, according to a Reuters poll.

Buttigieg's campaign said Monday it had received donations from all 50 states, with an average donation of $47.

"Pete has proved why he is a top-tier candidate for the nomination," campaign manager Mike Schmuhl wrote in an email to supporters Monday.

"From town halls on MSNBC, CNN, and FOX News to last week's debate, he's shown the country what I've known for a long time: Pete is the best person to bring a new generation of leadership to Washington."

Bernie Sanders was the third big name Democrat whose campaign released its fundraising figures this week, with the Vermont senator's campaign saying it raised $18 million in the second quarter.

The fundraising tallies for the surging campaigns of Harris and Sen. Elizabeth Warren have yet to be released and hotly anticipated in Washington.
