The “Deep State” is the convenient scapegoat for your representative to blame when he fails to do as he said to do, and who he promises to fight if re-elected.
I remember Limbaugh was promoting cross-over voting in 2008 to ensure that Hillary didn’t get the Democrat nomination. He was encouraging Republican voters to go and vote for Obama in the primaries so that McCain would not have to face Hillary in the general election. I believe that his reasoning was that Hillary was well entrenched in the political system and that Obama, being a relatively young, new-comer to the system, would not be nearly as effective at getting things done if he were to win the election.
