Senate Minority Leader Mitch McConnell had his best fundraising quarter of this election cycle, pulling in $2.4 million in the first fundraising quarter of 2014.
But McConnell is also spending heavily. His campaign will report $10.4 million in cash on hand, which is down more than $500,000 from his cash position when he started the year.
The McConnell campaign emphasized that the spending is not in response to a primary challenge from Louisville businessman Matt Bevin, saying that the majority of expenditures are for the fall campaign.
An ad that McConnell's campaign ran earlier this year featuring Paducah cancer survivor Robert Pierce ran statewide at a cost of more than $840,000.
"Team Mitch has invested early in ground-game infrastructure that will help deliver unprecedented voter contact in Kentucky," the campaign said in a statement to the Lexington Herald-Leader. "Additionally, last quarter, Team Mitch made their first major television expenditure with an ad that media guru Frank Luntz recently called the best of the cycle."
McConnell has raised more than $2 million for four consecutive fundraising quarters, having raised a total of $22.3 million this cycle.
Jesse Benton, McConnell's campaign manager, said that McConnell's "re-election campaign has been executing a comprehensive, long-view strategy on the ground, internet, mailboxes and airwaves to ensure victory in November."
"We are proud of the outpouring of support from people across the country who appreciate that Sen. McConnell is the number one impediment to the Obama agenda of Obamacare and the war on coal."
Bevin said Monday that his campaign raised $1.1 million in the first quarter of the year.
Candidates across the country were releasing their fundraising totals Monday ahead of the April 15 reporting deadline.
Bevin's campaign didn't release how much cash it has on hand to spend in the remaining six weeks before the primary, and the official report was not yet posted on the Federal Election Commission website.
