DSCC Chairwoman Murray: Ted Cruz is Mitch McConnell's problem

Murray maintained her confidence that the party would retain control of the Senate. She said that while Republican outside groups had spent $55 million so far, outspending Democrats by a 3-to-1 margin to date, the DSCC would help even the playing field going forward. She pointed to the group's $7 million money edge over the National Republican Senatorial Committee and the cash advantage most of their candidates had over their opponents.

"The right-wing groups have had a real monopoly on the television airwaves but that is going to change now," she said.

The DSCC chairwoman attacked Republicans for backing Rep. Paul Ryan's (R-Wis.) plan to partially privatize Medicare, and promised wins in nearly every state the party is competitive in, though she did admit Nebraska was a tough battle.

When asked how likely she thought it was that the Senate would remain in Democratic hands, she joked about Senate Majority Leader Harry Reid's (D-Nev.) statement that there were 50-50 odds his party would keep control.

"In terms of odds I am not from Nevada so I don't do odds," she said.
