The Democratic Senatorial Campaign Committee (DSCC) out-raised its GOP counterpart once again and has a cash advantage heading into the campaign homestretch.

The DSCC bested the National Republican Senatorial Committee in June, bringing in $8 million to the NRSC's $4.4 million. The Democrats now have $31.4 million in the bank to Republicans' $24.3 million.

Helped by the party's majority, the DSCC has outpaced the NRSC in fundraising for most of this cycle, though its advantage on that front is likely to be more than counterbalanced by the big edge GOP super-PACs will have in spending on down-ballot races this fall.
