Bitter GOP primary for South

Businessman and self-described outsider Toby Doeden will advance to a runoff for the GOP nomination for South Dakota governor, CBS News has projected, after a competitive and frequently contentious primary.

1. Frame 1Toby Doeden's advance forces South Dakota GOP voters toward a July 28 runoff over taxes and governing power.
2. Frame 2No candidate is on track to reach 35%, so Tuesday's primary cannot settle the Republican nomination.
3. Frame 3Gov. Larry Rhoden, Rep. Dusty Johnson, and House Speaker Jon Hansen are fighting for the second ballot spot.
4. Frame 4Rhoden took over after Trump chose Kristi Noem for Homeland Security, then ran for a full four-year term.
5. Frame 5Doeden has lent his campaign roughly $4 million and is campaigning on property-tax phaseout and spending cuts.
6. Frame 6The July 28 runoff decides which Republican faces Democrat Dan Ahlers in a GOP-favored November race.
