Barack Obama grasps a small 1.5 percent lead on Mitt Romney in pre-election Colorado polls, but the GOP challenger surged past the president among early voters.

Mr. Obama's support rests at 48.8 percent to Romney's 47.3 percent in the state, according to Real Clear Politics (RCP). PPP gives the president a wide 6 percent lead, 52 percent to the Governor's 46 percent. WeAskAmerica depicts a smaller edge, with Romney at 47 percent and Obama  at 50 percent. Denver Post/SurveyUSA and CNN/Opinion Research each place Obama 2 percent ahead of Romney. Rasmussen Reports shows a Romney advantage of 3 percent, with the Republican  securing 50 percent while the president holds onto 48 percent. ARG puts Romney 1 percent ahead at 48 percent to Obama's 47 percent.

RCP records a margin of error of 3.0 percent for PPP, 2.9 percent for WeAskAmerica, 3.8 percent for Denver Post/SurveyUSA, 4.0 percent for Rasmussen Reports, 3.5 percent for CNN/Opinion Research, and 4.0 percent for ARG.

The Associated Press Election Research Group shows that 1,872,987 Colorado residents have cast early ballots. Of these votes, 34.3 percent were Democrats, 36.1 percent were Republicans, and 29.5 percent were none/other.

In a video report NBC's Mike Taibbi explains, "What both sides agree on is that if there's not a projected winner by the time counting starts in Colorado, this could be a key, if not the key state as the night goes on."
