Our favorite local food site has been doing some thinking about politics and the way people in different cities eat and vote. They divided the number of steak restaurants by the number of sushi restaurants in a given city to come up with a "Steak/Sushi Index." Seattle's SSI, for example is 0.75, indicating that we eat more sushi than steak; the SSI of Dallas, TX is 3.01 indicating a preference for steak. Urbanspoon has been able to show that the more a city eats sushi over steak (or the lower their SSI) the more they tended to vote for Kerry over Bush in the last election.
Cities tend to vote primarily Democratic, but you can see on the graph below that cities with more steak restaurants than sushi restaurants voted for Kerry in smaller numbers, or, in the case of Dallas, actually preferred Bush.

Check out Urbanspoon for more. They even track the ascendancy of sushi or steak through time to predict the outcome of our next presidential election.



This makes me never want to eat sushi again.
