I don’t know about a likely replacement, but Priebus isn’t any conservative and he’s a butt buddy of Ryan’s and Walker’s neither of whom have been in Trump’s corner from the get-go. Frankly, I was concerned about Priebus’ appointment when it was announced.
I have NEVER trusted Priebus. He and Paul Ryan are snakes. It would not surprise me if both were among the swamp dwellers leaking plans and conversations to the libs and media.
