South Dakota Gov. Larry Rhoden fended off a primary challenge from businessman and Bitcoin evangelist Toby Doeden on Tuesday, winning the first gubernatorial primary runoff in state history and advancing to the November general election. The election marked the first time South Dakota voters were asked to settle a gubernatorial nomination through a primary runoff. He went further by calling for South Dakota to establish a state Bitcoin reserve – a move state investment and budget officials opposed. In the run-up to Tuesday's primary runoff, property taxes were among the defining issues of the campaign.
