Republican Greg Lopez won a special election to serve out the remainder of Rep. Ken Buck’s (R-CO) term in the House.

The Associated Press called the race for Lopez, a former Parker, Colorado, mayor, 32 minutes after polls closed on Tuesday, defeating three other candidates to replace Buck, who left Congress early on March 22. The former mayor won 57.3% of the vote, with 79% of votes counted in Colorado’s 4th District.
