Here's the first reaction from the addled old short guy's camp:
""Today, Barack Obama has revealed himself to be just another typical politician who will do and say whatever is most expedient for Barack Obama," said communications director Jill Hazelbaker in a statement. "The true test of a candidate for president is whether he will stand on principle and keep his word to the American people. Barack Obama has failed that test today, and his reversal of his promise to participate in the public finance system undermines his call for a new type of politics."
Personally, I would question the judgment of a candidate who would forego 10's of millions & a huge competitive advantage because of something he filled out on a questionnaire close to a year ago. That would be idiotic, and I've had enough of idiotic over the past 7+ years to last a lifetime.
