Incumbent Democrat Michael Bennet and his Republican challenger Ken Buck are in a virtual tie in Colorado’s U.S. Senate race as the candidates prepare for a nationally televised debate on Sunday. The latest Rasmussen Reports telephone survey of Likely Voters in Colorado shows Buck with 47% support to Bennet’s 45%. Four percent (4%) prefer another candidate in the race, and another four percent (4%) are still undecided. (To see survey question wording, click here.)
These findings move the race from Leans Republican to a Toss-Up in the Rasmussen Reports Election 2010 Senate Balance of Power rankings. This is the closest the race has been in eight months of surveying.
Less than two weeks ago, Buck, a county prosecutor, held a 50% to 45% lead over Bennet, who was named to the Senate last year when Ken Salazar joined President Obama’s Cabinet. In surveys since March, Buck has earned 44% to 51% support, while backing for Bennet has ranged from 38% to 45%. (Want a free daily e-mail update? If it's in the news, it's in our polls).
