Poll: Bennet trails in Colo. Senate race

Colorado's Senate contest remains tight less than a month from Election Day with prosecutor Ken Buck (R) leading Sen. Michael Bennet (D-Colo.) by just five points--50 percent to 45 percent.  

Two percent of likely voters prefer someone else, while four percent remain undecided. 

The new Rasmussen numbers paint a picture of a race without much movement over the past few weeks. The last Rasmussen poll in the race from late September gave Buck a lead of 51 percent to 43 percent--it was the first time the challenger crossed the 50 percent threshold in Rasmussen's polling.  

The poll surveyed 750 likely Colorado voters and has a margin of error of plus-or-minus four percentage points.
