Jenny Sanford is the soon-to-be ex-wife of Mark Sanford, the Governor of South Carolina.  He made headlines a few months ago when he was “hiking the Appalachian Trail,” which apparently means admiring your “soul mate’s” tan lines in Argentina.

Jenny has a book out now, and is doing some media to promote it.  She talked to Barbara Walters the other day.

Among the many revelations from the interview was this:

South Carolina first lady Jenny Sanford recalls how she made the “leap of faith” to marry husband Gov. Mark Sanford even though the groom refused to promise to be faithful, insisting that the clause be removed from their wedding vows.
A Barbara Walters interview, this Friday on 20/20 10/9c.

“It bothered me to some extent, but … we were very young, we were in love,” she said in an exclusive interview with Barbara Walters to air on “20/20″ Friday. “I questioned it, but I got past it … along with other doubts that I had.”

Uh… Jenny?  When a guy goes out of his way to remove the faithful clause in your wedding vows, that’s what we call a big flashing warning sign.  (By the way, you were 27 when you were married.  You had graduated from college.  That hardly counts as “very young.”)

From the rest of the interview, it seems like Mark has always been a nut.

“He drew me a picture of a half a bike, and then for the next birthday or Christmas I got the picture of the other half a bike, and then he delivered the $25 used bike,” she recalled.

For another birthday, Mark Sanford gave her a diamond necklace, which she adored, but then he took it back.

I’m just glad the implosion happened when it did, since this guy had “rising star” status in the GOP.  I’m glad his star was quashed before he did too much damage.  (Just goes to show you, nuts can be fiscal conservatives too.)

I’m not excusing Mark’s behavior here, but Jenny, really, what did you expect?
