DENVER (AP) A new poll shows Democratic Sen. Mark Udall of Colorado may not cruise to re-election next year.
The Quinnipiac University poll released Tuesday puts Udall ahead of all GOP challengers. But only 41 percent said Udall deserves to be re-elected.
Udall's lead was nearly within the margin of error against Republican Ken Buck. Buck was the GOP nominee three years ago against Colorado's other senator, Democrat Michael Bennet.
The poll also asked Coloradans about presidential possibilities. Several Republicans tied or beat former Secretary of State Hillary Clinton.
The poll of 1,206 registered voters was taken from Nov. 15-18 and has a margin of error of plus or minus 2.8 percentage points.
