On Newt's "Open Marriage" Request

Apparently the second Mrs. Gingrich (of three) gave an interview, to be aired later tonight as a palate-cleanser from the Republican debate (yes, another one), from which the so-called "bombshell" headline is that Newt asked her whether she'd be okay with an open marriage. This would be around the time when he was cheating on her with the third and current Mrs. Gingrich, an indiscretion he says he's sought forgiveness for from god, etc. etc. But I can't see why this would be that much of a bombshell: don't we already know he was, you know, cheating on her? That's old news, right, and fully priced into everyone's opinions of Newt already? Isn't it kind of de minimis at worst, and arguably not even a negative, if he also, you know, asked permission to cheat? I mean, for me anyway it's an emphatic positive (although the part where, on being told "no," he goes ahead and cheats anyway is not so hot): having clandestine affairs without telling your spouse/partner is a genuine wrong that you've done them, whereas asking if they're okay with your having an affair and then, with permission, having said affair is not a wrong at all. Perhaps it'll sound all San Francisco-y to South Carolina Republicans, but I still think that it's just not categorically different than the existing body of Gingrich sex scandalousness.

Maybe they'll prove me wrong, but I'd be a bit surprised.
