The DSCC has outraised the NRSC every month this year except April. 

The DSCC haul brings its total this year to just under $31 million. The NRSC raised about $2.66 million last month, according to an official, which brings its total to just over $20 million for the year.  

An NRSC official noted that the committee has reduced it’s debt to $5 million, down from $6.5 million last month — half the debt the DSCC holds. 

Cash on hand totals were not immediately available, but as of June, the NRSC had $7 million cash on hand and $6.5 million in debt while the DSCC had $9.6 million cash on hand and $11.2 million in debt. 

The executive director of the DSCC gave credit to new Democratic Senate hopefuls in Kentucky and Georgia — Alison Lundergan Grimes and Michelle Nunn, respectively — for partly sparking Democratic fundraising. 

Democrats are facing a tough election cycle in 2014 but currently hold a five-seat advantage in the upper chamber with Cory Booker poised to win a special election in New Jersey. However, the party is defending 21 seats, including six in states Republican presidential candidate Mitt Romney won in 2012.
