As Hillary Clinton bounded to the stage after a mammoth win in Kentucky last night, Barack Obama spokesman Bill Burton did his best to steal her thunder. In an email to reporters, Burton announced details of the camp's fundraising numbers for April, a month in which Obama again outraised both his rivals.

Obama raised $31.9 million in April, though $600,000 of that money has to be saved for the general election. The campaign attracted 200,000 new donors, bringing their fundraising base up to 1.475 million, and still has $37.3 million on hand for the primary election. A staggering 93% of the donations were in amounts under $100 (94% were under $200, leading one to believe the Obama campaign doesn't ask for a lot of $150 checks).

Clinton came in second with a not-unimpressive $22 million raised in April, much of it from her campaign's big win in Pennsylvania on the 22nd. That victory brought in $10 million in 24 hours, the campaign reported, and the total amount does not include the $5 million Clinton loaned her own campaign that month, as Ben Smith points out. It's the second-best month Clinton has had this year.

Bringing up the rear, but with good news of his own, John McCain raised $18 million in April, his best month of the campaign, as ABC News reported yesterday. The Republican is on pace for another good month, after raising an impressive $7 million in one event in early May. He has already hit fundraisers in Illinois, Georgia and Florida, and he travels to California later this week to raise more coin.

Next week, McCain will host an event in Phoenix with President Bush, and the president will also hold fundraisers with former Massachusetts Governor Mitt Romney in Utah.

So far this cycle, Obama has raised $264 million, while Clinton has pulled in $193 million to date. McCain's campaign lags far behind, having raised just $89 million to date, a figure almost three times less than Obama's totals.
