Yet another swing state drops into Romney's column after a terrible week in the polls for President Obama and the Democratic ticket.

Colorado, which Obama has clung to for months, seems to have drifted into Romney's corner, according to a new CBS News/New York Times/Quinnipiac University poll released Thursday.

With 48 percent of the vote, Romney just edges out Obama, who stands at 47 percent.

Another poll by ARG gives Romney and even bigger lead, 50 percent to 46 percent. Previous polls by Rasmussen and the University of Denver just a few days ago showed Obama still in the lead.

But Colorado was the site of Obama's terrible performance in the first presidential debate last week. Viewers in Colorado overwhelmingly said Romney won that debate, 72 percent to 16 percent.

The Huffington Post, which is tracking 35 Colorado polls, gives Romney the thinnest of margins in the state, half a percent, leading Obama 47.5 percent to 47 percent.

Real Clear Politics, which has several running aggregates of both state and national polls, puts Romney 0.6 points ahead of Obama, 47.6 percent to 47 percent.

And FiveThirtyEight gives a current snapshot of Romney up by just a tenth of a percent in Colorado, though the site still predicts Obama will eke out a win, giving him a 51 percent chance of taking the state, along with its nine electoral votes.

This is just one bit of bad news for Obama. Other polls released today show Romney taking the lead in four other swing states. Obama's popularity has been dropping, but Democrats had hoped that a strong showing in swing states would prevent Romney from winning in the Electoral College, no matter how well he does nationally.

Still, swing states do just that. Voters in those states are notoriously ambivalent, and tonight's vice-presidential debate or next week's second presidential debate may convince some of them to rethink their allegiance yet again.
