Bill Keller’s upcoming column for the New York Times’s Sunday magazine, “ Asking Candidates Tougher Questions About Faith ,” raised familiar liberal paranoia about the conservative religious views of Republican presidential candidates Mitt Romney, Michele Bachmann, and Rick Perry. The official headline for the upcoming print edition: “Not Just Between Them and Their God.” Keller had no time for respectful criticism: “Mitt Romney and Jon Huntsman are Mormons, a faith that many conservative Christians have been taught is a 'cult' and that many others think is just weird.” Keller, the outgoing executive editor for the Times, got off on the wrong foot by mockingly comparing the candidates’ Christian beliefs to belief in space aliens. Then he made the latest in his impressive string of column factual errors , identifying the Catholic politician Rick Santorum as an evangelical Christian. If a candidate for president said he believed that space aliens dwell among us, would that affect your willingness to vote for him? Personally, I might not disqualify him out of hand; one out of three Americans believe we have had Visitors and, hey, who knows? But I would certainly want to ask a few questions. Like, where does he get his information? Does he talk to the aliens? Do they have an economic plan? Yet when it comes to the religious beliefs of our would-be presidents, we are a little squeamish about probing too aggressively… … This year’s Republican primary season offers us an important opportunity to confront our scruples about the privacy of faith in public life — and to get over them. We have an unusually large number of candidates, including putative front-runners, who belong to churches that are mysterious or suspect to many Americans. Mitt Romney and Jon Huntsman are Mormons, a faith that many conservative Christians have been taught is a “cult” and that many others think is just weird. (Huntsman says he is not “overly religious.”) Rick Perry, Michele Bachmann and Rick Santorum are all affiliated with fervid subsets of evangelical Christianity, which has raised concerns about their respect for the separation of church and state, not to mention the separation of fact and fiction.
