A new Quinnipiac poll in Colorado finds Sen. Mark Udall (D-CO) just ahead of Ken Buck (R) in a possible re-election match up, 45% to 42%.
Udall holds slim leads over five other possible GOP challengers as well.
Said pollster Tim Malloy: “Though running even or ahead of six possible Republican challengers, Sen. Mark Udall must be pulling for a quick fix of the Obamacare website and a change of heart by Coloradans who dislike the Affordable Care Act by a wide margin.”
