Why do you think Fundamentalists push so hard for their followers to spew forth babies like Octomom?

That is their long term plan: mass production of babies that can be brainwashed from birth into a fervent belief of the fundamentalists' particular brand of religion and politics.  Read about the "quiver of arrows" movement.  They know that converting adults with an ounce of reason is nigh impossible, so they go the production/brainwashing route.

There was a study several years ago, that showed that religious/rightwing people were outbreeding secular/liberal people.  This has been going on for a while, and probably accounts for a large chunk of the 25% that still supported Bush when he left office.
