A series of television ads from Colorado's appointed senator, Michael Bennet, appears to have given his election hopes a boost as a new Rasmussen poll (500 LVs, 4/5, MoE +/- 4.5%) shows him narrowing the gap with two of three potential GOP foes. His primary opponent, former Colorado House Speaker Andrew Romanoff, has lost ground against all three.
