DENVER (AP) — Republican Rep. Cory Gardner is leading Democratic Sen Mark Udall in Colorado, according to a new independent poll released Thursday.
The 48-40 Gardner lead among likely voters in The Quinnipiac University Poll contrasts with two other independent polls released earlier this month that found Udall tied or slightly ahead in the race. It is from the same pollster that found Democratic Gov. John Hickenlooper 10 points behind his Republican challenger, a finding that also conflicted with other polls that have shown that race essentially tied.
The Quinnipiac poll surveyed 1,211 voters by telephone from Sept. 10-15 and has a margin of error of plus or minus 2.8 percentage points.
The Colorado Senate race is one of the most competitive and expensive in the nation. Republicans need to pick up six seats to win control of the chamber.
