Why You Shouldn't Eat Your Young

This isn't the first time I've run across this topic. I don't know why it's published as an opinion piece, because it just lists the facts.

Simply put, liberals have a big baby problem: They're not having enough of them, they haven't for a long time, and their pool of potential new voters is suffering as a result. According to the 2004 General Social Survey, if you picked 100 unrelated politically liberal adults at random, you would find that they had, between them, 147 children. If you picked 100 conservatives, you would find 208 kids. That's a "fertility gap" of 41%. Given that about 80% of people with an identifiable party preference grow up to vote the same way as their parents, this gap translates into lots more little Republicans than little Democrats to vote in future elections. Over the past 30 years this gap has not been below 20%--explaining, to a large extent, the current ineffectiveness of liberal youth voter campaigns today.

It reminds me of another article I posted more than a year ago.

The Roe effect, however, refers specifically to the nexus between the practice of abortion and the politics of abortion. It seems self-evident that pro-choice women are more likely to have abortions than pro-life ones, and common sense suggests that children tend to gravitate toward their parents' values. This would seem to ensure that Americans born after Roe v. Wade have a greater propensity to vote for the pro-life party--that is, Republican--than they otherwise would have.

That is more of an opinion piece, but is seems like prophesy.
