Why Is McCain Advocating For The Murder Of A U.S. Senator?

Barack Obama is still a U.S. Senator and under Secret Service protection. Regardless, if anyone at any candidates campaign rallies shouted "kill him" it is the responsibility of that candidate to immediately denounce the comments. John McCain did nothing. Again - JOHN MCCAIN DID NOTHING!

This is sick and a look into how McCain feels about American politics and America as a whole. I really hope that Obama finds a way to work this in to tonight's debate. The American people should know that McCain is apparently content with people wanting to murder our leaders. That's terrorism you can believe in.
