ROCKY FORD, Colo. (AP) -- A Democrat who's trying unseat a Republican congressman in a newly drawn district knows the odds are against him.

Brandon Shaffer is trying to oust Republican Rep. Cory Gardner in a sprawling eastern Colorado district where registered Republicans outnumber Democrats by more than 15 percentage points.

Shaffer is a state Senate president and an attorney from Longmont north of Denver.

The party margin in the new 4th Congressional District gives it the makings of a slam dunk for the GOP. But Shaffer is focusing not on the big gap facing him but on a much smaller number -- the percentage of people who like what Congress is doing. Shaffer is hoping to capitalize on anti-incumbent sentiment.
