Mike Rounds has clinched the Republican nomination in South Dakota's Senate race, the Associated Press reports.
Rounds, who served as South Dakota governor from 2003 to 2011, will face Democrat Rick Weiland in the race for outgoing Sen. Tim Johnson's (D-S.D.) seat. The race is seen as critical in the battle for control of the Senate.
Earlier this week, The Huffington Post's Amanda Terkel and Samantha Lachman offered details on the contest:
Former Gov. Mike Rounds (R) has been the GOP frontrunner in the race to replace retiring Sen. Tim Johnson (D-S.D.), although state Rep. Annette Bosworth (R) has been getting a fair amount of attention in the five-person Republican primary. In April, she likened food stamp recipients to wild animals. Still, Bosworth has lagged in the polls and her campaign has been in debt. Rounds, meanwhile, has focused on the failings of Washington and said Congress needs to focus more on debt reduction. A candidate must get at least 35 percent of the vote in order to receive the nomination, otherwise a run-off between the top two finishers will be scheduled. The winner will face Democratic businessman Rick Weiland, who was once a staffer for former Sen. Tom Daschle (D-S.D.).
