I stuck to my guns regarding my Pennsylvania predictions, and at least this time they didn’t misfire or singe my fingers. Clinton’s 10-point, 220,000-vote walloping of Obama last night advanced her a bit further along in her longshot bid to win the popular vote and thus the superdelegates.

Now we come to the May 6 primary in North Carolina, where Obama has just refused a Democratic debate invitation and a new Survey USA poll has him at only 50 percent.
