Even my overrated capacity with numbers is overwhelmed by last night. Too much to read and absorb. I have just a bunch of random impressions that just maybe, as they used to tell me in that long-ago aborted time in grad school, will contribute something original to the literature.
That early vote margin gave the impression of a 20 point Hillary landslide on first glance, when you were only looking at the Clinton-Obama numbers. That gap has now closed to about 9 points, but it's that first impression of a fast California call that lasts.
Obama seems to do well in states where there are either a huge number of black voters or virtually no black voters at all. In states with large urban populations, and ethnic suburban populations, he doesn't do as well. In other words, either a state needs to have white voters who have very little experience with ethnic or racial politics, or it needs to have an extremely large black population, in order to vote for Obama.
This one reminds me of waaay back in college, where guys like me from lily white parts of outstate Wisconsin were innocent-clueless about race and the guys from midtown Milwaukee had a bunch of black best friends, but the guys from the suburbs had a bad attitude. In any case, that wouldn't bode well for Obama in places like Pennsylvania or Ohio.
