What Trump HAS done is exposed the GOP as a party that is not monolithically a "small government" party. Indeed, it has shown the GOP to be, clearly, a majority-statist party, with a number of their statists quite OK with what "pure" conservatives and libertarians might view as "Nanny Statism". I think we are at the end of the road where Movement Conservatives can honestly assert that the reason the GOP loses is because it's candidates "aren't conservatives". I would suggest that the last two GOP nominees were, in fact, to the right of the ideological midpoint of the GOP.
Good post.
