When is John McCain going to take a stand?

I think John McCain is a decent man. I have qualms with his policies and his sometimes erratic behavior, but I understand that he's under a lot of pressure right now being so far behind in the polls.

What I don't understand is his unwillingness to take a strong stance and fight back against the hate being spewed forth by some of his supporters. Every time someone yells out "terrorist!" or "kill him!" in reference to Obama, right in front of McCain, and McCain doesn't harshly rebuke it, I lose a little respect for him. If he truly wants to be the President for all Americans (not just the pasty white ones that show up to his rallies), then he needs to stand up for all Americans to the intolerance and hate that seems to be taking over his and Palin's rallies lately.

I realize that not all McCain supporters condone this sort of behavior, which is exactly why they too need to take a stand. There is no room for this sort of behavior to become acceptable in the United States. It's downright frightening actually. Regardless of who our candidate in this election is, those of us who are reasonable and decent people need to stand together to say "hell no" to this kind of racist, intolerant, and vile hatred.
