Pollster John Zogby predicts President Obama will become "toxic" for Democrats on the campaign trail if incumbent Sen. Michael Bennet loses to state legislator Andrew Romanoff in Tuesday's Democratic primary in Colorado. In an exclusive Newsmax.TV interview, Zogby says a loss by Bennet, a favorite of the Democratic establishment who has received strong personal support from the president, would send a clear signal to other Democrats, sharply truncating Obama's coattails come November.
