Migth just be me - but wasn't there a tinge of race to that ad? Referencing the "historic" nature of today as a reference to King's I Have A Dream speech is what I believe the McCain camp was reinforcing. Hoping for better from McCain but resigned to possibility it's meant to evoke racial considerations.

Well, I think that since he was congratulating Obama on becoming the first black nominee, it would be impossible to completely sidestep race. I don't think there was anything underhanded about it.

Trust your gut feeling. You have the ad pegged. It is a shout out to white racists. John is desperate and he knows who his base is.
