Another thing that I've noticed is that it also optimizes for moderates/centrists, since that's where the Nash Equilibrium is[1].
With the growing polarization in our politics, I think that the political spectrum in the U.S. now looks less like a Gaussian distribution and more like a bimodal distribution. At this point the median voter is becoming a smaller and smaller plurality, and the equilibrium is becoming unappealing to more and more people.
