Even better, they've broken us down into conservative and liberal buckets, which is perhaps more straightforward than it
sounds, since someone who's a fan of Rush Limbaugh, Mitt Romney and the American Enterprise Institute is probably fairly conservative (this kind of «sentiment
analysis» can be a real pain to
automate when you're talking about individual social media posts, but I suspect it gets easier when you can figure in someone's overall pattern of social behavior, as Facebook can).
