In addition, it is a HUGE signal about the moral compass of the GOP (there is none) and a signal about what sort of judges McCain would pick.
As the writer says later, “He is often conservative, but he is certainly not part of the conservative movement, and would never qualify as one of the vaunted true conservatives in the eyes of the movements luminaries. The base has to let this go. McCain won the nomination fair and square, and McCain is going to do things his own way.”
Reminding the base of this just as he is starting to be competitive is NOT a good idea.
