I’ve got news for you: The greatest president in modern American history would have been impeached from office by around February 2017 without his party standing behind him, which include some pretty lousy and unreliable people but people who fear the GOP rank and file to some degree.
That’s not to say all of them are worth retaining. We’re better off with Flake gone, but you’re on crystal meth if you think Romney is in the same league as him or Kasich. If your cutoff is anyone no less reliable than Jim Inhofe, you might as well surrender now because the left’s takeover will be completed overnight. Thankfully, the base isn’t dumb enough to adopt your loser strategy.
If Trump isn't supported fully by the Republican party through 2020-2024, I'll be voting 3rd party or Independent. It's up to them.
