About twice as many people have no political views as have a coherent political belief system.

[...] Man may not be a political animal, but he is certainly a social animal. Voters do respond to the cues of commentators and campaigners, but only when they can match those cues up with the buzz of their own social group. Individual voters are not rational calculators of self-interest (nobody truly is), and may not be very consistent users of heuristic shortcuts, either. But they are not just random particles bouncing off the walls of the voting booth. Voters go into the booth carrying the imprint of the hopes and fears, the prejudices and assumptions of their family, their friends, and their neighbors. For most people, voting may be more meaningful and more understandable as a social act than as a political act.

That it is hard to persuade some people with ideological arguments does not mean that those people cannot be persuaded, but the things that help to convince them are likely to make ideologues sick - things like which candidate is more optimistic. For many liberals, it may have been dismaying to listen to John Kerry and John Edwards, in their speeches at the Democratic National Convention, utter impassioned bromides about how "the sun is rising" and "our best days are still to come." But that is what a very large number of voters want to hear. If they believe it, then Kerry and Edwards will get their votes. The ideas won't matter, and neither will the color of the buttons.

I'm pretty stuck on Louis Menand's "The Unpolitical Animal" in this week's New Yorker
