The National Republican Senatorial Committee has more cash in the bank going into the summer than its Democratic rival. 

The NRSC announced Monday it banked $18.1 million, compared to the Democratic Senatorial Campaign Committee's $17.57 million by the end of May. Strategists for the GOP were quick to note that this time last year, Democrats were ahead by close to $17 million.

The DSCC, however, continues to outraise the NRSC, pulling in $5 million to its $3.6 million last month. Neither committee has any debt.

Meanwhile, NRSC Chairman John Cornyn (Texas) sent out an e-mail fundraising pitch Monday that focused on Nevada Senate candidate Sharron Angle (R).

"This is one of the most important races in the country this year," he wrote. "Sharron Angle and our candidates need your support. We plan to be heavily invested in Nevada and many other states but we need your help to do to it."

He asked supporters to give to the NRSC "so we can help her fight and win in Nevada."
