I have a story in today's paper analyzing some of the undecided superdelegates. Even though many of them are from districts that overwhelmingly backed Sen. Hillary Clinton, they are still withholding their public endorsements.

Several superdelegates from Indiana, Pennsylvania and Ohio are bucking the will of the people by withholding endorsements from Sen. Hillary Rodham Clinton, staying silent even though she overwhelmingly won their districts.

The silence from dozens of superdelegates who have good reason to back Mrs. Clinton amplifies the near impossibility of her winning the Democratic presidential nod.

The schedules of Mrs. Clinton and her rival Sen. Barack Obama revealed their priorities: She campaigned in three states while he spent yesterday wooing superdelegates among Democratic lawmakers on Capitol Hill.

While Mr. Obama received a rock-star welcome, signed autographs and posed for photos, Mrs. Clinton told voters that they must ignore pundits who have counted her out more times than she can count.

Read the full story here.

A spokeswoman for Rep. Chris Carney of Pennsylvania told me late yesterday he hadn't backed a candidate, but later last night Clinton scooped up his endorsement. His district went solidly for Clinton on April 22.

Obama picked up two members of Congress last night - Rep. Donald Payne of New Jersey switched from Clinton to Obama and Rep. Peter DeFazio of Oregon endorsed him. DeFazio will campaign with him in the Beaver State today.

My colleague Sean Lengell has an update on the Florida and Michigan mess in today's paper.
