Trump's most loyal supporters, especially Evangelicals, see him as their biggest defender and no matter his flaws, they believe he is their David to Goliath.  

Guess it's kind of like having a flawed bodyguard that is willing to fight all your battles - you could not care less how flawed the bodyguard is as long as he fights your battles.

These fools will only get over this guy when they learn he is nothing more than a bullying PT Barnum and would sell them down the river the first chance he gets if he has to. 

Frankly, as I've said before, I think it really comes down to race and greed.  And when I say race I mean a deep down pathological think; almost a reptilian thing.
