From Michelle Goldberg's recent piece on Michelle Bachmann:
[A]ccording to Randall Balmer, who is both an evangelical and a historian of American evangelicalism at Columbia University, it was the born again Jimmy Carter who first marshaled the era's newly awakened Christians. "He brings them into the political arena. There's no question about that," says Balmer. "And the great irony is that they turned so rabidly and rapidly against him four years later."
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.
