DENVER _ President Barack Obama leads Gov. Mitt Romney 50 percent to 46 percent in the last of four live-interview polls tracking the presidential race in Colorado.

The poll – conducted Friday, Saturday, and Sunday – is the latest in a series of tracking polls released by Keating Research, Inc. and OnSight Public Affairs. It marks the first time the President has reached the 50 percent mark since tracking began in August.

“Obama’s advantage with key demographic groups like unaffiliated voters and women has given him a narrow but sturdy lead at the end of this election cycle,” said pollster Chris Keating. “It certainly appears that Colorado will come down to which campaign can turn out voters.”

More than two-thirds, or 69 percent, of Colorado voters have already cast ballots, and among those early voters, Obama has a 5-point advantage with 51 percent supporting Obama and 46 percent supporting Romney. The President leads 48 percent to 45 percent with voters who said they had not yet cast a ballot.

In a state where more voters are registered unaffiliated than Democrat or Republican, Obama leads by 25 points among unaffiliated voters with 58 percent backing the President and 33 percent supporting Romney. Unaffiliated voters are seen a key factor in this race because candidates have locked up support with their base voters. Registered Democrats give 92 percent support to Obama with 5 percent supporting Romney while 92 percent of Republicans favor Romney to just 6 percent who favor Obama.

The President is also getting overwhelming support from Hispanic voters, with 73 percent support to Romney’s 21 percent support. Romney leads by 5 points with white voters with 50 percent favoring the GOP candidate while 45 percent support Obama.

Obama has maintained a significant lead among women in Colorado, and he holds a double-digit lead on the eve of Election Day. Fifty-three percent of women favor Obama, while 43 percent support Romney. Romney leads Obama among men 48 percent to 47 percent.

Previous OnSight/Keating polls this cycle showed Obama maintaining a narrow lead:

For this sample of 603 interviews, the worst-case margin of error at the 95% level is plus or minus 4.0 percent.  Respondents were chosen at random from a list of likely voters with phone numbers, including cell-phones.
