Larrison Campbell, a female reporter with Mississippi Today, revealed this week that she had asked to shadow Foster for a day on the campaign trail. Two of her colleagues were already following other contenders, but Foster turned down Campbell’s request — unless, that is, she brought along a male colleague. The reason? He obeys the “Billy Graham rule,” refusing to be alone with any woman other than his wife, or, as he put it, “avoid any decision that may evoke suspicion or compromise of our marriage.”

Criticism followed, and Foster bristled at it: “The liberal left . . . can’t believe, that even in 2019, someone still values their relationship with their wife and upholds their Christian Faith,” he tweeted.

But unfortunately, there’s not a single inch of moral high ground achieved via the Billy Graham rule, which purports to honor marriage vows. In similar fashion, Vice President Pence once said he would not dine alone with a woman to whom he wasn’t married. But rules like these don’t honor your wife. They just presume that your marriage vows are so flimsy that you can’t be trusted to uphold them unless a babysitter monitors you. It’s rather like a thief sanctimoniously announcing that he brings a parole officer every time he goes to the bank to make sure he doesn’t rob it. Good for you, dude, for knowing your own limitations — but it doesn’t make you better than the rest of us, who manage to regularly not steal things even when we’re completely alone.
