By the time all the shit has hit the fan if that's even possible
I have a feeling a lot of Trump supporters will deny ever supporting Trump. Or that the delivery of a satisfying and deserving "I told you so" will be met by a vigorous defense of themselves saying; you took their "support" (trust me, they'll use airquotes) of him too literally, that they never really supported Trump at all they were just being patriots and supporting the office, that the liberal media never gave him a chance, or they'll stick with the good old defense that Hillary would have been worse (in which case, of course they would not have been patriots supporting the office).
I work with these people like a lot of us do, and I'd love nothing more than to pipe in with a good I told you so, but they will never believe or admit that Hillary would have been a better president, or even a less bad president, than the worst president in history.
big reagan fan, - who insists to the end, 'nixon got a raw deal'.
They will NEVER believe that Trump is a narcissistic criminal. They are committed to the "deep state" and "fake news" canards that shield them from truth and facts about their racist political messiah.
Removing Trump by impeachment or election will not silence him or the hate machine that props up the dangerous messages. TRUMP TV will carry messages of conspiracy, grievance, and victimhood for a long time.
