The Michigan primary happened today. Trump won handily with nearly 70% of the GOP vote. Biden also won, but nearly 100,000 Democrats voted "uncommitted" which basically was the anti-Biden, pro-Hamas vote.
If these "uncommitted" Ds sit out the November ballot, Biden probably loses Michigan. If they vote for Trump, it is a rout. Data from RealClearPolitics.
Next Tuesday - March 5 - will be Super Tuesday, when a whole bunch of states and territories hold primaries. There's a good chance one or both of the major party leading candidates will have enough delegates to ensure nomination a week from today.
