After two polls earlier in the week showed President Barack Obama still ahead in Colorado, Republican challenger Mitt Romney's post-debate bounce appears to have finally stretched into the Centennial State, according to two new polls from ARG and Quinnipiac University/CBS News/New York Times.

With less than 30 days to go until Election Day, the latest poll from Quinnipiac/CBS/NYTimes released today shows Romney leading Obama 48 percent to 47 percent in the state, within the poll's margin of error. Last month the same poll gave the edge to Obama who lead Romney by a one-point margin, 48-47.

And no surprise, those surveyed overwhelmingly said that Romney won the debate at University of Denver -- 72 percent chose Romney, while 16 percent chose Obama as the winner.

The Quinnipiac poll comes just two days after an American Research Group (ARG) poll that showed Romney with an even larger lead: 50-46. The last time ARG polled the state in September, Obama was leading Romney by two points.

Both of these polls arrive just days after a Rasmussen poll and a University of Denver poll both showed Obama still leading in Colorado -- Rasmussen gave Obama a one-point lead, University of Denver gave Obama a four-point lead.

The HuffPost Pollster estimate, currently tracking 35 polls in the state, shows Romney ahead of Obama by just a half-percentage point in Colorado, 47.5-47. Although a slight edge, it is the first time the Republican challenger has pulled ahead in the Pollster model for Colorado during the 2012 polling cycle:

Nationally, Obama holds a very slight lead of less than a half-percentage point, according to the HuffPost Pollster model, currently tracking 503 polls, 47.1-46.7:
