Limbaugh is a prime example. Rush is a Liberation and Blobalist that pretends to be a Conservative.
My hope for this Presidency was that it would shake up the racket, and it has to some degree, but with the departure of people like Steve Bannon from the WH, who knows if that will continue.
Today's "conservatism" is basically liberalism with slightly lower taxes and some lip service to social issues. On immigration, trade, and foreign policy you'd have a hard time distinguishing Paul Ryan from Hillary Clinton.
That's the strategy of uniparty - pretend to be mortal enemies on an issue or two while walking hand in hand on the fundamentals.
