Missouri Secretary of State Robin Carnahan (D) kicked her fundraising operation into high gear in the first quarter, raising $1.5 million for her Senate campaign.

Rep. Roy Blunt (R-Mo.), meanwhile, announced via Facebook that he raised $1.3 million. It is the first time since the first quarter of 2009 in which Carnahan has outraised Blunt over a three-month period.

Carnahan announced the total, which is her best since launching her campaign, in an e-mail to supporters. Her campaign separately told The Hill that it raised its cash on hand from $2.1 million to $2.8 million.

"I'm so pleased to let you know that we're filing our quarterly fundraising report today and we finished strong -- in fact, we raised nearly $1.5 million in the first quarter of 2010!" The most we have ever raised in a single quarter to date," she wrote. "What a terrific grassroots team effort. I can't tell you how humbled and honored I am to have your support and support from all across Missouri, in every county."

Blunt maintains a $3.5 million to $2.8 million advantage in cash on hand. Blunt outraised Carnahan handily last quarter, pulling in $1.3 million compared to $877,000 for the secretary of state.

Carnahan is likely to face Blunt in the general election to replace retiring Sen. Kit Bond (R-Mo.).

Updated at 1:18 p.m.: The initial totals for last quarter failed to include money raised for a joint fundraising committee.
