Stuck in the Middle

Now this from the Times Online is interesting:

The more daughters there are in a household, the more likely the parents are to vote Labour or Liberal Democrat. In an unpublished paper that has been submitted to an economics journal, the pair declare: “This paper provides evidence that daughters make people more left wing. Having sons, by contrast, makes them more right wing.” The academics go on to speculate that left-wing families become so through a predominance of females down successive generations.
