"As someone who favors gay marriage, I think this Sanford scandal underscores a central truth. The anti-gay-marriage forces are stuck making a slippery-slope argument when, in fact, we’re already at the bottom of the slippery slope. Here’s a guy, Sanford, who has not just not a moral and religious incentive to keep his marriage vows, but also a political-survival incentive. Yet the public sense of the sacredness of marriage has declined to the point that even he couldn’t do it. How much more could this institution be eviscerated, by letting a tiny, tiny minority of same-sexers join it? (Gays are a small fraction of the population, and the percentage of them who want to get married is a small fraction of the small fraction. The issue is, as the lawyers say, de minimis.)", - Mike Potemra, NRO.
