Rep. Cory Gardner, R-Colo., is looking better and better in his campaign to unseat incumbent Sen. Mark Udall, D-Colo., with the latest batch of polling data showing the Republican challenger ahead by seven points, according to a USA Today/Suffolk University survey released Wednesday.

The survey of 500 likely Colorado voters shows that 46 percent prefer Gardner, while only 39 percent say they’re going to go for Udall.
