Political natural selection

Captain's Quarters takes a look at an interesting theory-that birth rates and abortions favor a "conservative evolution." The theory, along with the ones he quotes, is intriguing as an intellectual exercise, but it neglects one big thing: Free will. Kids break with their parents' political affiliations all the time. Political lines redraw themselves over time. Ideas live on and pick up new proponents, proponents whose families may have rejected it. When it comes to the world of political philosophies, I'd much rather have strong ideas on my side than Darwin.
