Jeb was so openly contemptuous & dismissive of conservatives nothing less than a humiliating smackdown would have done. And thats exactly what he’s getting.
Behind closed doors his father was always angry and contemptuous about Conservative Republicans. I remember a Time Magazine article from 1992 that quoted him saying (about right wingers) “F@#$ those people. There’s no satisfying them”. So this is the kind of thing Jeb has been hearing since forever. His father and brother possessed enough sense and discipline to control what they said in public and put up a credible pretense. Both men, one a Navy aviator, first US ambassador to Red China, and director of the CIA, and the other a pilot of a widow-maker mach 2 interceptor and hard drinking Hell raiser who reformed himself by finding Jesus and the love of a good woman, are at least real men. Jeb’s the flabby spoiled baby brother who lacks all that and probably resents the fact that he’s expected to carry on the family business.
