I agree with GP that a primary missing feature is a principled public - without principles people swing wildly in opinion depending on the topic and popular rhetoric.

I see this with much of my own family. They mostly consider themselves conservatives and Republicans of the small government and balanced budget era. Those presumed values go out the window though and when a particular political topic of the day comes up they seem to completely contradict it. The most egregious example in my family is a Ron Paul libertarian that somehow still holds those opinions while supporting virtually everything Trump does.
