This blog post at the NYT has some fun graphs up showing how various cable networks, alcoholic beverages, cars, and fast food chains skew Republican or Democrat.
It turns out that our family drives on the center-left side of the road, as we own a VW and a Toyota, both favored by Dems. (I suspect the Toyota numbers vary a lot by model, and that the eight-seater Sienna we drive probably shows up to the right of, say, the Prius.)
I don't watch enough TV or eat enough fast food to register very well on those measures, and I don't have enough brand loyalty to Big Beer to register much on the alcohol spectrum as well.
Being rather interested in bipartisanship, I was wondering what cultural forces can bring people together. It turns out that we can all get along by watching HGTV, A&E, and Spike; driving Chevrolets; dining at Wendy's; looking up movie listings on the Internet; and, in the one behavior I think I can endorse with reasonable enthusiasm, drinking Guinness. Now at least you know what to serve at those uncomfortable family get-togethers.
