"What's the Matter With Greenwich?"

Why did the rich vote against their own economic interests? Slate's Daniel Gross wonders:

I've theorized that people who work in financial services and related fields have become so outraged and alienated by the incompetence, crass social conservatism, and repeated insults to the nation's intelligence of the Bush-era Republican Party that they're voting with their hearts and heads instead of their wallets.

... As the campaign entered its final weeks, Barack Obama, who pledged to unite the country, singled out one group of people for ridicule: those making more than $250,000.... And yet the exit polls show, the rich—and yes, if you make $250,000 or more you're rich—went for Obama by bigger margins than did the merely well-off. If the exit polls are to be believed, those making $200,000 or more (6 percent of the electorate) voted for Obama 52-46, while McCain won the merely well-off ($100,000 to $150,000 by a 51-48 margin and $150,000 to $200,000 by a 50-48 margin)....

Obviously, "What's the Matter With Greenwich?" parallels "What's the Matter With Kansas?," which questions why people in lower-income groups vote conservative.

It seems to me that there are plenty of people who don't think that voting is about pursuing dollars for yourself. I know I don't. I think about what is best the country as a whole (and about the world). Am I a chump, to be puzzled over by newspaper columnists? Shouldn't we public-spirited voters be praised for taking our role seriously and understanding it correctly? Instead we're treated as if we are deluded.
