After President Obama won Colorado last year, many believed the state was trending blue. However, Colorado Sen. Michael Bennet (D), appointed this year to fill the vacant seat, trails three potential Republican opponents in a new Rasmussen poll (Dec. 8, 500 LV, MoE +/- 4.5%).
Bennet's favorable rating remains low, with 39% viewing him favorably and 46% unfavorably. All three Republicans -- Jane Norton, Tom Wiens and Ken Buck -- also lead Bennet's primary opponent, Andrew Romanoff.
