I'll make it simple for you my friend.
Republican voters love Trump, they support Trump by 90% + consistently. Throughout his presidency and at this very moment this is true.
Republican insiders don't support him at the same level, many career politicians oppose him. But here's their problem, they get destroyed by Trump time and time again. They lose their seats and they lose support because we the people are behind Trump.
Like democrats and their media, this makes them hate Trump even more. Like the democrats and their media, they played the same rolls in 2016. Like the democrats and their media, they lost. Let's not pretend the likes of George Conway, Bill Kristol, the Bushs and even the Mitt Romneys of this world ever supported Trump. Romney used Trump to win his election, then went back to being Mitt Romney
The Tea Party movement was and is real, and Trump's our guy. The Beltway crowd doesn't move us from him because we despise them and everything they represent in the political arena.
Everything they say about Trump is a lie. He's a racist, he's inciting racial tensions, he's sexist, he lies....... four fucking years of moronic hate filled bullshit from his political opponents (which include the morons you're citing) has only galvanized us.
Finally, any man that says he's a Republican and that he supports the Republican platform then turns around and endorses Biden is a fraud. That's simply not an option for any man that thinks like me
