Hanna , I actually think the “Who’s the nut bag?” ad is a very effective deployment of a chagrined spouse, even better than Hillary’s long-ago, “I’m not some little woman standing by my man like Tammy Wynette,” defense of Bill. Roxanne Wilson strikes an authentic note of being appalled by his remark and grateful that the president accepted her husband’s apology. It allows the viewer to agree his behavior was unacceptable (while reminding voters his violation was not so bad as some other South Carolina politicians), then Roxanne gets to remind people he sometimes gets carried away because he cares so much. Unlike so many stiff and phony politicians, she’s a natural in front of the camera. Maybe Mark Sanford, et al. should hire Roxanne to defend them!
