This sounds like my experience with conservatives. From William Saletan in today's SLATE:

A longitudinal study suggests whiny kids grow up to be conservative. They "turned into rigid young adults who hewed closely to traditional gender roles and were uncomfortable with ambiguity. The confident kids turned out liberal and were still hanging loose, turning into bright, non-conforming adults with wide interests." The authors suspect "insecure kids look for the reassurance provided by tradition and authority," whereas "the more confident kids are eager to explore alternatives." This matches a 2003 analysis that suggested "people who are dogmatic, fearful, [and] intolerant of ambiguity … are more likely to gravitate to conservatism."

Saletan takes issue with some of the methodology...you can read his reservations in the original if you want. It's my blog and I'll edit selectively if I want to...
