Former NRCC Chairman Tom Davis (Va.) pegged the GOP's chances of retaking the House at 50 percent or more.

While Davis was dubious that Republicans can retake the Senate, at least at this point, he was more optimistic about the House. Asked what odds he would place on it, Davis said: "50-50, at least."

"It's far from done," Davis said a breakfast hosted by the Christian Science Monitor. "You have to run races and execute. But they have put in all the pieces you need to do it, in terms of recruitment."

Davis put the lower boundary for GOP gains at 20-25 seats and the upper end at 55.

Davis said he thought Republicans had their best recruiting cyce in modern history. But he cautioned that DCCC Chairman Chris Van Hollen (Md.) has done a good job preparing the vast majority of incumbents for their reelection bids by helping them stockpile cash.
