Michael Barone thinks it portends favorably for McCain.
"Polling suggests that the Democratic nominee may not be able to count on the losing candidate’s tribes in November. Academics and young people and blacks may not turn out in extraordinary numbers for Clinton, as they have for Obama, and the upscale may prefer McCain to a tax increase.
Similarly, Jacksonians, the elderly, the downscale, and Latinos may prefer the very Jacksonian McCain to Obama. All of which should worry the superdelegates who must determine who wins the Democrats’ tribal war."
This is all leading up to one inescapable conclusion: The Dems will never see the truck that hit them on election day.
