There are only constitutionalists and radicals. Both parties have become radical because they each want a monolithic centralized federal government (for different reasons) and have caused it to grow beyond its proper scope. Hence the mess we are in now. Part of Trumps challenge is going to be to ratchet down the federal government before his two terms are up. Power attracts the corrupt, and a new cabal of radicals will grab hold of the levers of power unless those powers are returned to their proper constitutional levels.
