Since I can't seem to stop making predictions I'll throw another one in here.
Trump will survive just fine doing Russia's bidding, banning Muslims, building a wall, ogling naked teenagers, grabbing pudenda, using the office to enrich himself, choking the planet, breaking promises and keeping his tax return secret forever.
If he self-destructs it will be over something tiny or at least trivial. Equal in importance to, say, Howard Dean's scream. Some small error in etiquette or chance remark will undo him. Trying to kiss Queen Elizabeth's hand, saying he doesn't follow football, forgetting the name of Canada's capital (if he ever knew it).
I'm probably wrong but oh well. He'll be in a crucible of scrutiny, his every move shadowed. If he wants to do something normal for him like cheat on his wife he'll have to take the Secret Service along. He will never again be allowed to drive on a public road, though I don't know if he cares about that. He's going to be a lot less free than he's ever been and I think it will take a toll. I take comfort in knowing he's probably out of his comfort zone. His life as he knew it is over.
