If McCain has any grit at all, he has to speak to this.
People have put themselves out and put themselves at risk on his behalf. If they can risk themselves for him, the least he can do is stand up and speak for them.
You can't expect the press or the Dems to do this for you. In their playbook its only negative when you answer back. McCain's people need to hear from McCain.
Are people afraid to put McCain/Palin signs in their yard - knowing they could be targeted?
Absolutely disagree.
McCain has done well by distancing himself from this kind of thing. He will be seen as a leader for his lack of escalation.
