You mean the "what's the probability that your vote is the deciding one?" That was interesting, but it seemed like a theoretical problem to me.
I would characterize what I'm doing here as a fairly standard calculation of the partial derivative dP/dV_i, where P is probability of a political outcome, and V_i is number of votes cast for a candidate in state i.
In this notation, they calculated some function of P'(0.5), where P' indicates the inverse of P(V_i).
Sam, this is interesting. Reminds me of the 2010 Gelman/Silver/Edlin paper for the Electoral College.
