Colorado: Romney 50%, Obama 46%

At Rasmussen:

Mitt Romney has now reached the 50% mark for the first time in Colorado and leads President Obama by four in the critical swing state.

The latest Rasmussen Reports telephone survey of Likely Colorado Voters finds Romney with 50% support to Obama’s 46%. Two percent (2%) like some other candidate, and one percent (1%) remains undecided....

Still, Colorado remains a Toss-Up in the Rasmussen Reports Electoral College Projections. But Colorado is the fourth swing state that has moved in Romney’s direction in the past week. Florida, Missouri and North Carolina have now shifted from Toss-Up to Leans Romney.

Yeah, well, the biggest worry is Ohio, but things are looking up there for the Republicans. See the New York Times, "Ohio Race Tightens in New Poll" (via Memeorandum). That's the Times' Quinnipiac, which is oversampling Democrats. Here's Rasmussen from two days ago: "Election 2012: Ohio President - Ohio: Obama 49%, Romney 48%." That's probably more like it, and we've still got election day, and the Romney ground game enthusiasm to factor in.
