Trump is the one candidate not owned my the banking/media complex. They're scared of what he could actually do.
I have a few American friends who are smart and not potatoheads, and they are actually interested in voting for the guy.
They are not as worried about what Trump will do as much as they are worried about losing control of the GOP to the rubes they have been pandering to since Reagan.
If your friends would rather vote for Trump over Clinton or Sanders there is a least a little potato in there. He is running for the office of chief wall builder. Has he even mentioned policy?
