Another (slim, but not super-slim) possibility: The republican primary in California actually matters. The last day of primary voting is June 7. Winner-take-all republican primaries in California, New Jersey, Montana, and South Dakota. Also voting in D.C., North Carolina, and New Mexico. If Trump needs some of those states to reach the number required to win the nomination on the first ballot, that would be interesting. The GOP would probably working hard to prevent him from getting those votes. And he’d be working hard to get them. And we’d be eating popcorn and watching.
