You are wrong with both conclusions. And you say I’m standing on hindsight - well yes, we call it history.
You can go ahead and blame Trump’s demise on perfectionists and on inside the beltway elites if you want. Sip your kool aid while you do. Trump’s demise is on Trump, pure and simple.
And while there was no FR during Reagan’s day, there was still critiques of Reagan and he was well vetted, and the conservatives still supported him by overwhelming majorities. They never would for Trump. I’m sorry, Trump is just not at all like Reagan. Never has. Never will be.
Nothing wrong with that per se, but it is what it is.
