I really used to think that Rush was genuine about conservatism.............. until he fell in love with a leftist.
I'll never listen to him again.
Rush used to take a run at the difficult issues during the Clinton Administration, but he'd stop short of the real meat. A poke, but not even a flesh wound. After noticing a few rounds of that jousting, I just relegated him to entertainment, and not so much a serious warrior for Conservatism.
I haven't had any reason to change that assessment, I am sorry to say.
