The 1st Quarter fundraising derby is nearing an end.

Cory Booker, aka Spartacus, just released his numbers, and they underwhelmed, as reported at NJ.com:

U.S. Sen. Cory Booker’s presidential campaign released its first fundraising figures, saying its $5 million in donations exceeded its goal. But Booker trailed several rivals for the Democratic nomination.

Booker, D-N.J., announced the figures in an email to supporters in advance of the April 15 deadline for reporting fundraising figures to the Federal Election Commission.

“This movement is strong, and getting stronger with new folks involved every day,” Booker wrote. “What we’re doing with these resources matters — we’ve invested heavily in building our organizing team, especially in early states. In a crowded field like this, a strong ground game matters so much.”

He said the campaign would report having more than $6.1 million in the bank entering April. He can transfer the $4 million sitting in his Senate campaign account to his presidential committee.

Booker’s fundraising totals trailed the amounts reported by U.S. Sen. Bernie Sanders of Vermont ($18 million), U.S. Sen. Kamala Harris of California ($12 million), former Rep. Beto O’Rourke of Texas ($9.1 million) and South Bend, Indiana, Mayor Pete Buttigieg ($7 million).

Put aside money.
