"t wasn't easy, but President Obama's endorsed candidate squeezed out a victory in Tuesday night's Colorado Senate primary. And it's being seen as a boon for the President, who has been beleaguered by sagging poll numbers and strong anti-incumbent sentiment. Incumbent Sen. Michael Bennet beat Andrew Romanoff, a former speaker of the Colorado House — who was endorsed by former President Bill Clinton — 54.2% to 45.7%, according to The Denver Post. Of course, it wasn't just the Obama effect that resulted in the victory. Bennet had an overflowing war chest, with more than 10 times the amount of cash on hand as his opponent as of late last month. Bennet's defeat would have been bad news for the President, who previously has stumped for failed Democratic candidates including Arlen Specter, Martha Coakley and Jon Corzine."
