Obama Set To Announce New Superdelegates After Pennsylvania Primary

The LA Times reports today on how Pennsylvania fits into the larger Democratic primary race, and has this following observation about Obama and superdelegates:

Today in Pennsylvania's hard-fought Democratic presidential primary, there will be a winner and a loser. But the winner might not be the one with the most votes....

Obama strategists said Monday that they expected to announce a series of additional endorsements by uncommitted superdelegates shortly after Pennsylvania votes. A strong showing by Obama in Pennsylvania would give superdelegates more comfort in coming forward, but a bad loss might send them back to the assessment stage.
