Chuck Todd, one of the best in the business as far as I'm concerned, sees some potential:

Those who love the Veepstakes will enjoy today's Obama speech, not for the substance but for the person who will introduce him: Michael Bloomberg. While the mayor says he's not endorsing anyone (yet?), this is the second time Bloomberg has given Obama a high profile photo-op (remember the meeting at that diner a few months back?).

Kos makes his top three VP picks here. Who would you draft to round out a Clinton or Obama ticket?
