I wonder how you will feel when one of these looney tunes attempts a violent act after being egged on by these idiots? Then you will be saying that such behavior is "incomprehensible" and your candidate cannot be "held resposible" for such criminal behavior.
It is totally irresponsible for someone who hopes to be POTUS to encourage such violent behavior, or to tolerate such behavior to be encouraged by anyone who deigns to speak in their behalf. McCain knows the history of this country. He surely is old enough to remember all the assassinations and attempts in the last 45 years. Shame on him and anyone who doesn't speak out against such behavior--I'll say it, bigotted behavior.
