With 98% of the precincts reporting, Hillary Clinton leads Barack Obama in Pennsylvania by a solid 55%-45% margin. Slightly more than I predicted, but I was close. In any event, this was a win and a margin Hillary needed, so she will fight on. It will be hard for her to win to nomination, but not impossible. This will give her a boost. That’s my analysis anyway. Watch for all the pundits to say the exact thing over and over on cable news while using lots more words.
