Donald Trump has accomplished one thing: He has almost singlehandedly turned national level Republican politicians, with a few exceptions, into a party of morally bankrupt and corrupt liars. But, it was not a great leap to accomplish that, given the likes of McConnell, Rand Paul, Jim Jordan, Nick Mulvaney, Ted Cruz and a number of others.
Almost all of em were exactly the same 5 years ago. He didn't change anything on a party level
I think he just accelerated their downward spiral.
