In a poll conducted September 14, following the first U.S. Senate debate of the fall, Rasmussen Reports shows Ken Buck leading Sen. Michael Bennet, 49 to 45 percent, among likely voters. Buck leads Bennet 46 to 43 when leaners are not included.

Buck earns 81 percent of Republican voters’ support, while Bennet picks up 86 percent. Buck holds a “slight edge” over Bennet among the state’s vast unaffiliated voter bloc, though Rasmussen does not supply specifics.
