The Donald is a deal maker. He'll compromise anything to do a deal, add to that he has no core principles and you got a perfect tool for the likes of Schumer and Reid. Reagan compromised, and he did make mistakes, like S1mpson/Mazzoli, but he kept his core principles in mind. When you have no principles its like setting off on a journey without maps or GPS, you'll go in whatever direction seems easiest.
The Donald is a showman and a marketeer, especially for himself, I'm just worried that he'll be the perfect lump of clay for the leftist serpents that inhabit DC. When things go wrong and the people get angry, they'll slither back into congress throwing stones, it'll be Trump that catches all the blame.
