The Iowa caucuses are less than a month away, which means it’s time for candidates for the Republican nomination to demonstrate whatever bona fides might appeal to a rural, right-leaning state that also loves education and farm subsidies. It’s kind of tricky, to tell you the truth, but Iowa conforms to the template of contemporary conservatism in at least one way: church people. The state is bursting at the Crocs with evangelical Christians. That’s good news for Rick Perry, whose professed religion is the one part of his campaign he has not yet screwed up. If Newt Gingrich somehow makes himself unlikable between now and then, a victory in Iowa might breathe new life into Perry’s bid. If only he could find some completely safe issue that appeals to religious voters but doesn’t require him to remember anything about policy or events. If only. Video after the jump.
