Considering the conservative nature of this state, the Republican primary is the only real contest in this gubernatorial election.
South Dakota has always been friendly to Democratic Senators and Congressmen, but not governors. I think the Democrats will go all in on the House race, but ignore the governor race.
Which is odd because its generally the opposite in most other places, but not the Dakotas.
Depends on who they can get and who the GOP puts up. If the GOP gets a row officer to run for the House seat then the Democrats don't stand much of a chance.
