But it's not just down there, it's everywhere. People are just tired of these Republican's and their smug "we don't have to listen to you" attitude (see Cheney's "So" statement). These guys are just not getting the message that the American people expect Congressmen to work for them and their wishes.
As far as Katrina goes, the last thing people wanted to hear is their representatives (Democrat or Republican) making excuses for Bush and the rest. They wanted action, not politics but all Republican politicians understand is how to play follow the leader even if he brings them off the edge of a cliff.
I agree with you on McCain. The only reason he has a chance right now is because he has this "Maverick" label and needs to keep it and appease the far right wing at the same time. That is a hard juggling act. Right now he is flip flopping running hard and fast to the right. He is even pissing off the American Legion in the process and if he loses their support, stick a fork in his old wrinkled ass.
