Is that surprising? I'd imagine the loser in every state's gubernatorial race is also trending down on Facebook. McCain? All washed up on Facebook, too, right?
I don't think it's surprising, but to watch the actual data change in real-time is fascinating. We're entering the era of real-time, fine-grained, high-scale opinon metrics like never before.
so create two index "funds", "avg number of likes of people who just lost an election" and "avg number of likes of GOP" and see if the former post-loss delta is more or less than the overall delta of the latter. i suspect that recently losing an election has a greater effect.
