A trio of new polls of Colorado's 2014 Senate race show incumbent Democratic Sen. Mark Udall virtually deadlocked with Rep. Cory Gardner, his lead Republican challenger.
The first poll, conducted by the Democratic firm Public Policy Polling (PPP) for the National Coalition for Safer Roads, found Udall leading Gardner by just 2 points, 47 percent to 45 percent.
The second poll, conducted by the firm Fabrizio, Lee & Associates on behalf of the U.S. Chamber of Commerce, found Udall trailing Gardner by a 2-point margin, 44 percent to 42 percent.
The third poll, conducted by Quinnipiac University, found Udall ahead of Gardner by just a single point, 45 percent to 44 percent.
Gardner's February announcement of his challenge to Udall immediately transformed the race into one of the cycle's most competitive Senate elections, further complicating Democratic efforts to hold the upper chamber.
Every survey of the race taken this year has found the candidates within 2 points of each other. HuffPost's polling model, which includes all publicly available surveys, gives Udall just under 46 percent and Gardner just under 45 percent.
The PPP survey was conducted April 17-20, using automated phone calls to 618 Colorado voters. The Fabrizio poll was conducted April 16-17 among 600 likely Colorado voters. The Quinnipiac poll was conducted April 15-21 among 1,298 registered Colorado voters. Both Fabrizio and Quinnipiac used live phone calls to both landlines and cell phones.
