If Obama can both reconnect his inspirational personal story to the American dream and create a counter-narrative of McCain selling his soul to the Rovian devil, he can take back control of the campaign narrative.
McCain will opt for war as the first choice, not the last choice. With America now embroiled in two wars in Iraq and Afghanistan, one has to worry about John McCain's desire to "bomb bomb bomb, bomb bomb Iran."
It's not just the left questioning Obama's principles over the FISA flap. His opponents are pointing and laughing at him for being a panderer and accommodationist. And Obama hasn't even voted on the bill yet!
