The Democratic Senatorial Campaign Committee raised nearly $7 million more than its GOP counterpart in the first three months of this year.

According to figures provided by the committees, the DSCC raised more than $5.2 million in March, which is about $2 million more than the National Republican Senatorial Committee brought in last month.

The monthly haul helped the DSCC record its best first quarter ever, raising $13.7 million over the past three months and ending March with $8.4 million in cash on hand. The NRSC raised some $6.9 million in the first three months and had $5.3 million on hand.

Monthly fundraising reports were due to the Federal Election Commission by midnight Saturday.

Republicans need a net gain of six seats to win the Senate majority in 2014. With the proliferation of outside spending in recent cycles, the DSCC pushed its incumbents to turn in strong first quarter fundraising reports.
