There was at least some tiny seed of cruel, right-wing logic to the Martha’s Vineyard stunt, i.e. “let’s see how you out-of-touch coastal elites deal with migrants when they show up in your state instead of ours.”
Shipping migrants to California doesn’t even make sense by that standard, because California already has more undocumented people than any other state. Our elected officials don’t spend as much time attacking and dehumanizing them.
