Sestak: 'Cold, brutal facts of reality'

From NBC's Domenico Montanaro
Former Admiral and Pennsylvania congressman Joe Sestak, an early and ardent supporter of Clinton's, said on MSNBC he'd like to see the New York senator be the nominee, but he added, "There are the cold, brutal facts of reality."

He then pivoted, however, in the same breath to Clinton's electability argument on the popular vote and her leading McCain (by wider margins than Obama) in polling in Ohio, Pennsylvania and Florida (Obama does not lead in Florida, per recent Quinnipiac polls). He brought up Puerto Rico and that potentially 450,000 to 500,000 could come out to vote there. And that even though the race is about delegates, if Clinton could win the popular vote, then perhaps, superdelegates would get behind her as the nominee -- though, of course, that would have to be by overwhelming margins.
