There's a new book out on the clustering of America. An excerpt from Alan Ehrenhalt's review:
Certainly it is a case that the two major parties have come to accept. Soon after the 2000 election, Bush pollster Matthew Dowd reported to Karl Rove that there wasn't much point in focusing any campaign on independents or moderate voters anymore. The country was too polarized, essentially along the cultural lines that Mr. Bishop lays out. "If you drive a Volvo and do yoga, you are pretty much a Democrat," Bush campaign manager Ken Mehlman said in 2004. "If you drive a Lincoln or a BMW and you own a gun, you're voting for Bush." Mr. Bishop would agree. He would simply add that the yoga people have clustered in one set of culturally segregated enclaves and the gun owners in another.
But what if you drive a Volvo and own a gun?
