"that one"

It might be just me, but I wouldn't be surprised to see an attack ad by McCain in coming weeks using the "N" word? I get the feeling that McCain is getting desperate. I think he really feels he is entitled to be President. He's inciting hatred. At recent at recent rally when McCain pondered;
"Who is the real Barack Obama?" Back came the cries of "terrorist!!"
I don't think he believes that. McCain should have spoken out to correct them.
It's a very poor reflection on the state of the republican campaign. Maybe he's hoping Obama will be assassinated? Is that a little Strong? What does "Main Street" think?
