In a major loss for the National Rifle Association, Democrat Jason Crow has beaten Rep. Mike Coffman (R-CO) in one of the most expensive races in the nation.

Crow won in Colorado's sixth congressional district while unabashedly calling for a ban on assault weapons, expanded background checks and restricting high-capacity magazines.
