Sen. Claire McCaskillClaire Conner McCaskillSenate blocks bill that opponents say weakens water pollution rules Senate GOP wary of new tax cut sequel GOP Senate hopefuls race to catch up with Dems MORE (D-Mo.) brought in $2.3 million for her reelection between January and March, exceeding her haul for the previous quarter by almost $1 million.

McCaskill ended the first quarter with almost $6 million in the bank, a Democratic source confirmed Tuesday. Her campaign spent about $1 million during the first quarter, when the freshman senator launched the first ads of her reelection campaign.

"Claire is humbled by the fact nearly 86 percent of her individual supporters gave less than $200," McCaskill's campaign manager, Adrianne Marsh, said in a statement.

"It's this kind of grassroots support that helps us continue to fight back against the outside special interest groups," she continued, "because you can rest assured Karl Rove's anonymous corporate backers are handing him checks with a few more zeroes with hopes of buying this election in Missouri."

McCaskill's fundraising team has picked up the pace from the fourth quarter of 2011, when she raised $1.4 million, and the third quarter, when she posted a haul of about $1.2 million.

The three Republicans vying for McCaskill's seat haven't yet released their first-quarter figures, which are due to the Federal Election Commission on April 15. The GOP candidates haven't been able to match McCaskill in the money race so far, but the eventual nominee will likely see an influx in cash from Senate Republicans and outside groups as they target McCaskill in the general election.

Rep. Todd Akin (R-Mo.), one of the GOP contenders, had $1.2 million stored up for his campaign as of the end of 2011. Businessman John Brunner had about $210,000 in the bank, but has indicated both an ability and willingness to self-fund his campaign. Former state Treasurer Sarah Steelman (R) had less than $600,000 on hand at the end of December.

The Hill rates this race a toss-up.
