Republican businessman Mike Pompeo has won Kansas' 4th Congressional District seat, keeping the Wichita-area district in the GOP column. Pompeo, who's a Republican national committeeman, defeated Democratic state House member Raj Goyle in Tuesday's election. The district had been represented for years by Republican Congressman Todd Tiahrt (TEE'-hart). But Tiahrt gave up a possible re-election bid this year to seek the GOP nomination for Senate, which he lost to fellow Congressman Jerry Moran. Moran won the Senate race on Tuesday.
