U.S. Representative Dusty Johnson holds the strongest position among Republican primary voters for the South Dakota governorship due to his consistent polling lead and extensive experience in Congress and state government. Recent surveys, including an April poll showing him at 34 percent support, place him well ahead of House Speaker Jon Hansen, businessman Toby Doeden, and incumbent Governor Larry Rhoden, each clustered near 17-18 percent. Multiple candidate debates in April have highlighted differences in policy emphasis and campaign organization, reinforcing Johnson's broader appeal while keeping the field competitive. With the June 2 primary approaching and a 35 percent threshold required to avoid a runoff, trader sentiment reflects Johnson's frontrunner status alongside the realistic chance that no candidate secures a majority outright.
