Colorado's 4th District
Weld County District Attorney Ken Buck won the GOP nomination to succeed Rep. Cory Gardner, R-Colo., in Congress.
Buck had 44 percent of the vote when The Associated Press called the race.
Buck was the GOP nominee for Senate in 2010, but his campaign stumbled after he made a handful of controversial statements. Buck entered the race for Senate again this cycle but later dropped down to the House contest when Gardner decided to run against Democratic Sen. Mark Udall. The race is rated Safe Republican by the Rothenberg Political Report/Roll Call.
