That's exactly what happened with Bachmann, who campaigned for Carter in 1976—she and Marcus even went to one of his inaugural balls—but soon tacked sharply rightward. A key moment in her political evolution, as for many of her generation, was the film series How Should We Then Live by the theologian Francis Schaeffer, who is widely credited for mobilizing evangelicals against abortion, an issue most had previously ignored. A Presbyterian minister, Schaeffer argued that our entire apprehension of reality depends on our worldview, and that only those with the right one can understand the true nature of things. Christianity, he argued, is "a whole system of truth, and this system is the only system that will stand up to all the questions that are presented to us as we face the reality of existence." Theories or assertions from outside this system—evolution, for example—can be dismissed as the product of mistaken premises.
This accounts for some of the bafflement that occasionally greets Bachmann's statements. "Michele Bachmann says certain things that sound crazy to the general public," says author Frank Schaeffer, Francis Schaeffer's son and former collaborator. "But to anybody raised in the environment of the evangelical right wing, what she says makes perfect sense."
