Relatedly, you can predict someone's vote in the last election very accurately by asking whether they have consumed sushi in the last 14 days. (This works less well in my kitchen.)
A particular style of Japanese or Japanese-inspired food which has become famous in America. In America, sushi consumption is a ridiculously effective proxy for political liberalism. A landslide victory in the presidential election in the United States splits the country 53:47. The split among people answering "yes" to "Have you eaten sushi in the last 14 days?" is closer to 85-15.
Neither of the major political parties in the United States has any ideological commitment for or against sushi, but the coincidence that people in one tribe eat it and the ones in the other do not makes it a good example of political tribalism. Incidentally, since politics is a signaling mechanism, I have had people (on both sides of the aisle) profess to be surprised at my political leanings due to the perceived mismatch between them and my non-political preferences. (I love sushi.)
Doesn't work 100% though. My girlfriend is completely obsessed with sushi, but she's hard-core Republican.
However, she is socially liberal. So who knows. I'm pretty apolitical as well.
We have here the top ten brands for either political affiliation. Notably, some appear on both sides. While it's perhaps interesting that those brands do so well on either side, it would be far more interesting to know which brands are supported almost entirely by one side or the other. For example, say Dodge trucks have 90% Republican supporters and 10% Democrat. If that's the case, I want to know about it.
Edit: Sushi's a better example, and not just because mine was fictitious.
Going heads up against Bing without such a large portion of the market seems like unnecessarily making life harder for yourself. A high-quality service like Google offers is useful to everyone, and seems like a neutral moneymaker to me.
