Poll after poll has proven that alot of GOP voters don't even believe half the stuff the hardcore republicans believe - they vote GOP Because they hate libs, not because they believe in tax cuts for the rich or half the other stuff.  It's why Trump can do all kinds of non-GOP things and still be supported - because most of the voters never cared about those issues anyways.

A great example is taxes.  Well over 60% of GOP voters support raising taxes on the rich while lowering them for the poor, yet once again the GOP s proposing the opposite.  

The GOP has lost touch with their own voters
