An excellent column from Michael Barone on the different appeal of Clinton and Obama:
The academic who hears the Rev. Jeremiah Wright declaiming, "God damn America," is not unnerved. He hears this sort of thing on campus all the time. The Jacksonian who watches the tape sees an enemy of everything he holds dear.
Barone, of course, isn't just sketching out a theory. He does some serious state by state analysis to prove the point. But if you're not too interested in the nuts and bolts, the Jacksonian vs. academic meme is explored about half-way down the page.
