Its Democratic counterpart reported bringing in $7.4 million in March, capping off a $17.7 million first quarter haul. The Democratic Senatorial Campaign Committee now has nearly $24 million in the bank, also with zero debt.
Addressing the DSCC's self-proclaimed best fundraising quarter in history, the NRSC pointed to the money raised during the 2010 cycle.
Although the DSCC ultimately outraised the NRCC by $12 million in 2010, Democrats lost seven Senate seats, the NRSC said in a statement.
Republicans need a net gain of four seats in the next election to take control of the upper chamber, where Democrats are currently in the majority.
