The open South Dakota At-Large House seat, vacated by incumbent Republican Dusty Johnson running for governor, favors the GOP at 92% trader consensus ahead of the June 2 primary, driven by Attorney General Marty Jackley's commanding lead in recent polls—68% to 12% over James Bialota per Mason-Dixon's April survey—bolstered by endorsements from Donald Trump and withdrawn rival Casey Crabtree, plus superior fundraising. This positions a strong Republican nominee in a Solid Republican district per Cook and others, where GOP winners took 72% in 2024 amid weak Democratic opposition from Nikki Gronli and an independent. Upsets could stem from a primary surprise, Jackley scandal, or national midterm wave, though historical base rates and state partisanship make these remote.
