Former Gov. Mike Rounds (R) won the Republican nomination for Senate in South Dakota on Tuesday night at just before 10 p.m.

The Associated Press called the primary for Rounds (pictured) at about 9:38 PM ET. Rounds was running in a multi-candidate primary for retiring Sen. Tim Johnson’s (D-SD) seat. He defeated Annette Bosworth, who earned national attention for press conferences in recent weeks drawing attention to sexist remarks with graffiti.

The race was called for Rounds with about 32 percent reporting.

Rounds will face Democrat Rick Weiland in the general election.
