Exactly right. Rush has always been a huge proponent of "the lesser of two evils" philosophy in politics and would even go so far as to belittle those who tried to tell him it guaranteed a downward spiral. And now he get's it? Too late Rush.
As I have said on FR before, the only time I remember him getting truly angry with a caller was in ‘94(?) when caller Karen from Whitefish Montana said that very thing to him and he basically told her to drop dead. In recalling that conversation, she was correct in every particular, and he was incorrect. What really got to him IIRC was when she called the GOP establishment “Happy conservatives.” His anger was palpable.
