David Frum is worried about the roughly 25 percent of Americans who would be disinclined to vote for a Mormon for president. (This is a potential problem for Republicans because several of the party's leading presidential candidates are members of the Church of Jesus Christ of Latter-Day Saints.) Before setting out to defend the Mormons against prejudice, Frum briefly examines Jacob Weisberg's 2006 attack on the faith and promptly dismisses its arguments on the grounds that they could be applied to the members of many other churches.

I agree that Weisberg's arguments are overly broad. But what, I wonder, would Frum make of these very different arguments, which are aimed at specifically Mormon theological commitments and their (possible) political implications?
