At the convention, he's just as likely to claim that Hillary would be a better choice than Obama. Not outright, of course, but read between the lines. If I were running for office, he's the LAST guy I would want to introduce me!
Charles Dudley Warner said it best: “Politics makes strange bedfellows.”
In this case, I think the probability of Obama getting screwed is fairly high. This introduction speech would not happen if Obama were not desperate enough to risk giving Bill the spotlight.
Lest anyone forget the last ‘help’ Obama got from Bill, Romney’s latest ad quotes Clinton on Romney’s “sterling business career..”
