Republicans are bearing more Republican children than Democrats are bearing Democrats. New party strategy: More offspring. According to this Wall Street Journal editorial:
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.
Democrats, you need to start churning them out if you want to stay competitive twenty years down the road. That, or get people to notice how much better a job Bill Clinton did than Mr. Bush.
