With an $11.6 million first-quarter total, the Democratic Senatorial Campaign Committee bested their GOP counterpart in the first three months of the year and reported a $5.6 million haul in March.

The National Republican Senatorial Committee reported $11.2 million during the first quarter and raised $5 million in March.

"The strong support we’re seeing so early in the cycle shows that we’re going to be in a position to not only protect our majority next year, but also play offense in 2012," DSCC Executive Director Guy Cecil said in a statement. "The Republican move to end Medicare and give more tax breaks to the very rich has fueled support from our base. Our campaigns around the country are seeing that their supporters are excited and engaged earlier than ever before, and that will make the difference next year."

The DSCC reported $5.5 million cash on hand and $4.8 million in remaining debt. The committee also touted strong fundraising from its Democratic incumbents, several of whom posted strong first quarters.

For the NRSC, March marked the committee's best month of fundraising in an off-year since the passage of the McCain-Feingold law, which enacted sweeping campaign finance reforms. The committee reported $1.4 million cash on hand and has $2.7 million in remaining debt — down from the $6.5 million in debt the committee reported after the 2010 midterms. 

“Since Senator [John] Cornyn [Texas] assumed the chairmanship in 2009, his finance goals for the NRSC have been three-fold — to be careful stewards of our donors’ money, to continue to close the fundraising gap with Senate Democrats and to ensure that not a single Republican candidate loses on Election Day because of a lack of financial resources," NRSC Executive Director Rob Jesmer said in a statement. "The NRSC met, and exceeded, those goals last cycle, and while we’re still up against a Senate Democrat majority and the fundraiser-in-chief in the White House, we are committed to building on this success and winning back the majority next year.”

Democrats face a tough Senate landscape next year, with 23 seats to defend. Republicans need a net gain of just four seats to take control of the upper chamber in 2012.
