1. Her fairly impressive "technical landslide" in PA means she must stay in the race. But her victory wasn’t big enough to give anyone real confidence that she could actually win the nomination. She’s stuck with being perceived as mean and negative for at least two more weeks. And the odds are close to even that she’ll win in Indiana and really be stuck with going all the way to the convention that’ll have no choice but to deny her the nomination. (Obama’s has no momentum at all right now; the late deciders in PA went for Hillary.)
2. The old line on the Democrats this year was that voters were having a tough time choosing between two fine candidates. But Democratic voting has obviously become rather negative: Lots of white, working class, Catholic Pennsylvanians voted for Hillary although they don’t really like her and don’t really think she can get the nomination. They were very often voting AGAINST Obama and for, as they say, the lesser of two evils. (I would actually prefer to say they were choosing their manly, witty, and effective Governor Ed Rendell over the wimpy and boring Senator Casey Jr.)
3. For a variety of reasons, Obama has become ever more clearly both an AFRICAN AMERICAN and CULTURALLY ELITIST candidate. This combination, of course, is the recipe for Democratic defeat for the last generation. The sooner the nomination process is over the better for Barack. He needs to return to unity, change, and hope that transcends... And he can’t do that as long as the Clintons are around to exploit his every misstep. All in all, Republicans have lots of reasons to praise the Democratic devotion to proportional representation.
