Thanks to Eschaton for this eye-opening political analysis.
The elections aren't about reaching centrists. Even the so-called self-identified independents are actually reliably tilted left or right, thus Bush's push to turn out evangelicals rather than go for mushy middle voters in 2004. Now, says this columnist, the balance of power is in the hands of unmarried women, who tend to vote Democratic. (Who can blame them, knowing the proclivities of men, particularly of the southern whitebread variety.)
