Michigan's primary is today for both parties. The month ahead is going to be a thrashing for Haley. She's down by 40-70 points in the upcoming primaries.
The Democratic primary won't be close, but there is an effort to vote "uncommitted" to protest the war in Gaza. Given the sizable Muslim and Arab populations in Michigan and Michigan's role as a battleground state in the 2024 election, it will be important to watch. Biden won Michigan by 150k votes, so even a tiny signal would be significant.
