He's so right about #5. See what's happened to Peter Thiel. People were calling for him to be fired because he supported a major party nominee. That's not a good sign for so many reasons.
Like, did anyone freak out about Marc Andreessen supporting Romney or any of Trump's primary opponents? Nope. Actually I take that back: lots of people on the right got real angry when he supported Hillary Clinton after it became clear Trump had cinched the nomination.
