DENVER, Colo. — As President Obama arrives in Colorado Wednesday for a two-day campaign swing, yet another new poll tells a different story about the race in this battleground state.

The survey from CBS News and Quinnipiac University shows Republican Mitt Romney leading Obama in Colorado by a 50-45 percent margin.

That’s in stark contrast to two polls released Tuesday, one of which showed Obama with a six point lead and another that showed the race in Colorado tied.

Obama’s approval rating in Colorado has slipped since June, as polls show 47 percent approve of Obama’s job performance while 49 percent disapprove. A month ago, 49 percent approved of Obama’s performance while 47 percent disapproved.

On the flip side, Romney’s favorability rating has improved. In June, 40 percent of Colorado voters had a favorable view of Romney, while 52 percent had an unfavorable view. Eight percent said they weren’t sure. In the new survey, 44 percent have a favorable view of Romney, compared with 51 who have an unfavorable view with only 5 percent who aren’t sure.

Obama will speech at Metro State’s Auraria Campus at 1 p.m. today. You can watch the speech live here.
