One of the reasons why many speculate that Obama has more superdelegates lined up to vote for him than his current list of pledged super delegates is due what I witnessed during last night’s Obama rally in Pittsburgh’s Petersen Events Center.

Both Jason Altmire and Mike Doyle sat in the VIP section of the event. Altmire attended the previous Pittsburgh Obama rally. Quite simply, you don’t attend these events as visibly as these guys do if you’re not supporting the candidate. My hunch is that after the Pennsylvania primary ends, Obama will snag the public endorsements of both Rep. Altmire and Rep. Doyle. By the way, Doyle is an interesting get for Obama, because his mentor, Rep. Jack Murtha, is a big Clinton supporter. Plus, he’s my Congressman.
