Scarborough still believes in those things.  The GOP has drifted.  They're now huge spenders (actually have been for some time), and they, over the last 20-30 years, have decided that big government is OK as long as it comes to dictating who should and shouldn't get married, and basically holding the view that belonging to a certain religion is superior than belonging to some others.

You should check out a clip of the Will McAvoy character from "Newsroom" talking about what it now means to be a Republican.  To me, it best illustrates where the GOP has gone off the rails.

As far as Trump goes....I agree...he hijacked the GOP....because the GOP allowed it to happen.  Take Ted Cruz--Trump bashed his wife's appearance and said that his dad helped kill JFK....and Cruz now kowtows to him.
