Kentucky Secretary of State Alison Lundergan Grimes's Senate campaign brought in more than $2.5 million from the end of July through September, her team announced Tuesday — besting the intake of her opponent, Senate Minority Leader Mitch McConnell.

Earlier this week, McConnell's campaign announced it raised $2.27 million during the same period.

Grimes, a Democrat, drew in more than 13,000 donors, compared with more than 6,000 tapped by McConnell, R-Ky.

Republicans, led by the National Republican Senatorial Committee, attempted to downplay Grimes's narrow fundraising victory by suggesting she should have brought in more money.

"The over/under was $5M for Grimes at a minimum," tweeted Josh Holmes, a former McConnell staffer now with the NRSC. "How can $2.5 be success when you get $1M in a single day?"

Holmes also pointed to the haul by Majority Leader Harry Reid's most recent Republican challenger, Sharron Angle, in October 2010, when she announced $14 million in fundraising for the third quarter. But that was just weeks before the election, whereas Kentucky voters won't choose a senator for more than a year.
