They could get very busy.
Yep. Trump's DACA offer would have covered 1.8 million of them, with a 10-year review cycle, and a path to citizenship. And the Dems turned it down. And Trump said yesterday that he knew they would, and I believe him. He also said that they were "catching hell" from the people affected and I believe that too.
That's a pretty significant betrayal. When your opponent offers you most of what you want and your ostensible friends say, "No, all or nothing!" and it turns out to be nothing, and those "friends" start high-fiving one another as if they've won some sort of victory, it gets pretty obvious that they're not really your friends at all. And from the Dems' point of view this isn't really a good time for that sort of epiphany. November is closing fast, and that was a terrible message to send.
