If they ratfuck him this time anywhere near as bad as they did last time, he'll run independent. In that case, Trump will win even more easily than I've been expecting since February 2017. Of course, Trump has a sort of death wish, so he could invade Canada or something and then Bernie would win without owing anything to the other face of the status quo party.

The most recent results (at 62% reporting, somehow not including urban areas, for many hours now) show Bernie winning the popular vote but trailing in convention votes. I hope I'll hear Democrats complaining about the Electoral College again soon...
