GOP strategist Rick Wilson takes down Donald in an interview with Chris Hayes. You have to see it to believe it.

Here’s a taste:

Donald Trump is not mentally fit to serve as president. Everything he thinks, he says. That’s not candor, that’s lunacy. [Republicans] are going to have to own every crazy word, every lunatic tweet, every racist statement out of this guy’s mouth for the next five months. They should be running for the hills.
