(CNN) - A new poll released Monday indicates Mitt Romney has a narrow edge over President Barack Obama in Colorado, a little more than a week before Election Day.
Forty-eight percent of likely voters in the state back the GOP presidential nominee, compared to 47% who support the president, according to the American Research Group survey.

The one-point margin is well within the sampling error, leaving the two candidates statistically tied in the crucial battleground, a state Obama turned from red to blue in 2008.
Four percent, meanwhile, say they are undecided, while one percent say they prefer another candidate. Among independents, the survey shows Obama ahead of Romney, 50% to 42%.
Monday's poll follows a separate poll by NBC News/Wall Street Journal/Marist released last week that showed the two candidates tied at 48%.
With nine electoral votes, Colorado is rated as one of eight "toss-up" states on CNN's Electoral Map. The state kicked off early voting on October 22, and according to general election turnout numbers released Friday, Republicans had a slightly larger turnout at 244,263 compared to 225,850 Democrats.
Both Romney and Obama campaigned in Colorado last week, and the president was scheduled to return to the state on Tuesday but canceled his plans to monitor conditions from Hurricane Sandy.
American Research Group interviewed 600 likely voters in Colorado from October 25 through October 28. The sampling error is plus or minus four percentage points.
