We're not going to change human nature any time soon. It isn't that we aren't rational -- we are rational -- but reason has limits.
Those wacky NRO guys -- Jay Nordlinger has spent a weekend in Vermont, and now he Understands The Noble Working Man:
.... here’s how I understand it: Modestly off people — “real Vermonters,” as some people say — are voting for McCain and Palin. Comfortably off people, such as those who own ski chalets, are voting for Obama and Biden. And the following has been frequently noted about the city of my residence, New York: The rich are voting Democratic. And those who work for them — driving cars, cleaning rooms, and so on — are voting Republican.
(I guess we know what "the math" is, now.)
The Nordlinger Effect is when non-rich people respond they’re voting like the rich jerk asking them who they’re voting for just so he’ll shut up and leave them alone.
For his part, Yglesias himself has pointed (unnecessarily) to the work of Andrew Gelman to demonstrate that rich folks in poor states (like Vermont) do in fact tend to vote for Republicans, while poor folks in poor states (like Vermont) do in fact tend to vote Democratic. Others in Yglesias's comment thread take the trouble to note (among other things) that you're not a real Vermonter unless you're born there (at least), all the ski chalets are owned by "flatlanders" from Connecticut, Massachusetts and NY (who won't be voting in Vermont, anyway), and that all the actual data demonstrates amply that "Vermonters of modest means" will be voting overwhelmingly for Obama. (As for housekeeping staff voting Republican: If he believes that, I've got this bridge I'd love to sell him...)
And how the hell Jay Nordlinger can use the phrase "of modest means" without blushing, I don't know. Maybe it's an internal manifestation of the Nordlinger Effect: Jay telling Jay what Jay wants to hear, so his brain will leave him alone.
