Rep. Cory Gardner (R-CO) has opened up an seven-point lead over Sen. Mark Udall (D-CO), according to a new Suffolk University poll.
The poll found Gardner leading 46 percent to 39 percent among likely voters. Back in mid-September, Suffolk gave Gardner just a one-point advantage, 43 percent to 42 percent.
It is the biggest lead that Gardner has seen over the last month, during which time early voting has already started; Fox News and Quinnipiac University had shown him up by six points earlier in October.
The Suffolk University poll, conducted Oct. 18 to 21, surveyed 500 likely voters. Its margin of error is 4.4 points.
According to TPM’s PollTracker average, Udall currently holds a slight edge, 46.1 percent to 46 percent.
