They’re back. Those political prognosticators who say they know how we’ll vote (or why). This time, two marketing firms say they have their finger on the pulse.

Of course, it’s only a matter of time before social psychologists will publish their findings on why we’ll vote the way we do in the upcoming presidential election.

Engage and GetTrendsetter, the two firms, have combined forces to analyze what your Facebook likes have to say about who you’ll vote for. In this neat graphic, they reveal that people who like, for example, Spotify, Buzzfeed, and Reddit are Obama all-the-wayers.

If you like, Bing, and Ebay, you’re most likely a Romney-ite. (Of course, there are several more examples).

(Our question: If Facebook likes reveal who we’re likely to vote for, what about people who don’t use Facebook or don’t bother to “like” sites if they do?)

Even though they’re totally predictable, we really enjoy the (biased) psychological research on the nature of liberals and conservatives and independents that start to sprout a few months before national elections. Here are some of our past posts on this and related topics:
