We'll see soon enough. If the big money donors start boycotting him, and the media manages to pin a toothbrush moustache on him, we'll know for sure he's the real thing.

In much the same way none will fundamentally change how the money supply will operate via the Fed. Electoral politics only goes so far When the uniparty is firmly in control.
