It would make sense due the fact Trump knew that running as a Democrat would never fly with the Clinton's next in line for the throne, and somewhere in the ether of my mind was a quote or a video of Trump saying in some interview (Playboy?) "If I were to run, I would run as a Republican because they are the dumbest group of voters in the country".
Of course we understand Northeastern liberals do believe that, so it's not a stretch to think Trump also thought or has voiced opinions to match it.
