Rep. Cory Gardner won’t challenge Sen. Mark Udall

Republicans have lost their top potential recruit in Colorado, with Rep. Cory Gardner (R) opting not to challenge Sen. Mark Udall (D) in 2014.

"I've got work to do, I'm not in a hurry to run for another office," Gardner told the Denver Post. "I think the most important thing for people is to know now. I needed to make a decision now, and I'm fully committed to make sure the GOP nominee will win in 2014."
