President Obama made an in-person push for health care reform in the Philadelphia suburb of Glenside today, but Hotline OnCall's Reid Wilson notes that some vulnerable Democrats from Pennsylvania were not in attendance for his speech.

Democratic Reps. Patrick Murphy, Chris Carney, and Tim Holden did not attend the event. Meanwhile, Senate primary combatants Arlen Specter and Rep. Joe Sestak were there.

Health care will figure prominently in the 2010 midterms, and vulnerable Democrats in swing districts figure to face attacks associating them with whatever form of health care Obama signs, assuming Democratic leaders in Congress manage to pass something significant.
