Since Jimmy Carter announced during the 1976 presidential campaign that he was a born-again Christian, the media have been fascinated by religion, but not so much that they would labor to understand it. Senate Majority Leader Harry Reid is a devout Mormon, but Mr. Reid gets a media pass on his faith because he toes the line on the secular left's agenda, from abortion to same-sex marriage, which Mr. Reid endorsed last week. That his church teaches the opposite of the way he votes doesn't appear to concern him. Sen. Orrin Hatch, also a Mormon, is running for re-election in Utah. Mr. Hatch is less scary to the media than some, because he made friends with the late Sen. Ted Kennedy, with whom he occasionally cooperated on legislation.
