Conservative donor class?
No such thing exists.
The donors advocate for their business interests. Not necessarily illegal, but it has nothing to do with conservatism.
Trump was never a liberal. That’s just a Cruz lie. He’s been a registered republican since 1980 and helped raise money for Reagan, Bush, etc. Check out his interview from 30 years ago that Ann Coulter retweeted a few hours ago.
But also 2) Koch brothers are conservatives. Why do you think libs hate them so much? I don't agree with Koch brothers on everything, but agree with them on MOST things and would trust Trump FAR more if he was accountable to someone like them whom I knew to be reliably conservative.
