From a Jonah Goldberg essay on NRO about the campaign polls and tensions in the Democratic Party, he gives one great line, at the end of the paragraph below:
Psephologist and columnist Michael Barone noticed during the primaries that, with the exception of the black vote, Obama’s support within the Democratic party is comprised almost entirely of cultural liberals. He dubbed this intra-Democratic split a divide between “academics and Jacksonians.” The Jacksonians are working-class, culturally conservative whites. The academics are the same people who formed the base for Howard Dean, Bill Bradley, Michael Dukakis, Gary Hart, George McGovern, and other successful presidents in the anti-matter universe where Spock has a goatee.
The rest of the essay is good as well.
