If the Obama surge in Pennsylvania is real, the race will be over on April 22. But what if it's not? Winning the expectations game (at least in the primaries) is pretty important. When Ohio and Texas went to the polls, Hillary had long been expected to win big in the former, but Texas...in the days before the election people started talking about the possibility of an Obama upset. When it didn't pan out, Hillary appeared that much stronger (even though she had been expected to win both for months), and Obama seemed staggered. You'd expect both sides to be working hard to lower expectations in Pennsylvania, but the Obama campaign has made big moves with a bus-tour, a major registration effort, and an overall attempt to make it seem like they believe they have a shot. Sure it could pay off huge and deliver the fatal blow to Hillary, but it's a gamble. If she wins by 10 points despite his best efforts, Obama will appear unelectable. Reporting like this makes me think that's still the most likely outcome.
