To rephrase Rousseau's famous dictum, "Everywhere man is born free, but everywhere he is looking for chains, that is to say, certainty." I think we all are victims of this human frailty. In distinguishing the greys of the political spectrum, the tails are a white (all colors of the spectrum) where total freedom, anarchy, creativity are to be found, and on the right where certainty, dogma, death and nihilism are to be found in total black (the absence of color). We are all somewhere in between and the median is constantly shifting with time. I'm not at all sure it's a Boltzmann distribution but I've been corrupted by Taleb's Black Swan.
By world standards the American voter is clearly to the right but that is changing more rapidly than we deserve to expect with every trampling of democracy. In the rest of the developed world public educational standards are higher along with consequent upward mobility giving more hope for the young. In the less developed world the challenges of poverty make for two kinds of leaders: despots or Francis look-a-likes who all too often end up as victims on the cross of greed and certainty.
