There's another interesting wrinkle in President Obama's trip to Pennsylvania today. The Morning Call reports that Sen. Arlen Specter (D) has joined Obama on Air Force One for the flight to Pittsburgh, just weeks after he was curiously absent from the state when the Republican-turned-Democrat could have used his support in the primary.

As for the winner of that primary, Rep. Joe Sestak (D) -- he will not be at the event today. The White House typically invites all statewide officeholders and local representatives; Sestak represents a Philadelphia-area seat. No doubt he could have attended if he wanted, though, but he likely will keep his distance from all things White House amid continuing questions about a deal offered last year in an effort to convince him to drop his primary challenge.
