The Democratic Senatorial Campaign Committee (DSCC) outraised its Republican counterpart by just over $3 million in the final month before the midterm elections.

The committee took in $17.4 million opposed to the $14.2 million raised by the National Republican Senatorial Committee (NRSC). For the entire cycle, the DSCC outraised the NRSC $107.1 million to 92.9 million. DSCC Executive Director J.B. Poersch said Tuesday the fundraising advantage helped prevent a GOP wave from sweeping Democrats out of power in the Senate like it did in the House.

“We were able to beat back Republicans this year because of the strong support from Democrats around the country," Poersch said in a statement. "In state after state, as Republicans nominated extremist candidates, our supporters became more energized. Senate Democrats exceeded expectations this year because we had better candidates with the resources they needed running aggressive campaigns."

Republicans made a net gain of six seats on Democrats in the Senate, diminishing their majority but falling short of taking control of the upper chamber. Democrats will begin next year with a 53-47 majority, down from a 59-41 advantage.

NRSC Chairman John Cornyn (R-Texas), who was unanimously selected Tuesday to lead the committee for another two years, expressed confidence last month that the GOP could take the Senate in 2012, when Democrats have to defend 21 seats as opposed to 10 for the GOP. He also lauded GOP gains this cycle, including winning President Barack Obama's old Senate seat. 

"Two years ago, few would have imagined that Senate Republicans would win seven Democrat-held Senate seats, while successfully defending every single Republican Senate seat," Cornyn said in a statement Tuesday. "And over the last two years, we were successful in adding nearly 400,000 new, first-time donors to the NRSC, we strengthened relationships with our longtime supporters and ultimately raised over $100 million. In fact, just last month, the NRSC raised $14.2 million, which represented the highest monthly total since the passage of McCain-Feingold in 2002."
