I recently had a lunch with a Trump supporter and it got me worried. This individual is a successful professional, wealthy, white woman in her mid-fifties; but not the stereotypical Republican trash: not racist of xenophobic, a Canadian immigrant in fact; not particularly religious; smart, world traveler.
She doesn't care about Trump's statements about Mexicans or Muslims, it's just campaign tactics. She doesn't idolize him for his wealth or celebrity status. But this person is just fed up with all US politicians and she ate Trump's outsider message bait, line and sinker. She's voting Trump because he is independent, non-establishment, self-funded. She doesn't even think Trump is particularly qualified to be a President, but she thinks he is a great manager and he's going to put together the most awesome team because he's not bound to campaign donors and Washington lobbyists.
And that's what should worry us in this election: not the extremists, not even the idiots; just reasonable folk who aren't particularly sophisticated in politics and fall to populist demagogues like flies over fresh excrement.
