A new Public Opinion Strategies/FMMMA poll in Colorado shows Sen. Michael Bennet (D) with a slight lead over challenger Ken Buck (R) for U.S. Senate, 43% to 40%.
Said pollster David Metz: "Bennet first had to make his case with members of his own party -- and he did that convincingly, according to this data. Now, he has to do the same thing with the voters that will be the deciding factor in November: Independents, suburban voters, and seniors, in particular."
