And this one could make a huge difference in the ability of the Senate to act decisively

Regardless of his party or politics, they guy is a slimeball for what he did to Max Cleland in 2002. Back then, McCain said, "[I]t's worse than disgraceful, it's reprehensible;" about Chambliss' ads. Since the campaign tactics haven't changed, it's reasonable to assume that McCain has lowered his standards.

My wife recently told me that she had received a piece of historical info from where I do not remember. She stated blithely (as historical fact) that since the Whigs were a party, Republicans have run by fostering fear, hate and anxiety. Ad hominum arguments are the preferred fuel of that engine. That is why John McCain is in Georgia. He's a skilled Republican, historically speaking.
