Party of the Sacred
This is a
great essay, that I've seen referenced in couple of different places, about why Republicanism resonates so well with a certain segment of the populace. (And it gives props to my Psych 101 Prof,
Drew Westen! He was one of the best profs I had at Michigan! And they let him get away....)
The writing style is a bit academic and tough to slog through, but give yourself 10 minutes and take it in. It's good stuff.
