Does anyone know what an “inappropriate physical relationship” even means? Does it matter, given the carnival nuttiness of the South Carolina GOP? First, let’s back up.

Mark Sanford, the sitting GOP governor, fell in love with someone who was not his wife, told his staff he was going backpacking, then flew secretly to Argentina and cried a lot. He came back home, his wife left him, and he has been trying to keep the flame alive with his Argentinian love by holding hands with her in Florida. Meanwhile, Nikki Haley, a Palin-backed conservative candidate, looks to have an inside track on getting elected the next governor of South Carolina.

But that’s not all. Today, a political blogger in South Carolina, Will Folks, wrote a blog post, which is either a terribly timed April Fool’s joke, a slanderous traffic play or one of the oddest admissions of infidelity in American political history. Folks writes that he has become the primary target of an anonymous group “that will apparently stop at nothing to destroy the one S.C. gubernatorial candidate who, in my opinion, would most consistently advance the ideals I believe in”–that is Nikki Haley. So in order to protect Haley and himself he admits the following:

The truth in this case is what it is.  Several years ago, prior to my marriage, I had an inappropriate physical relationship with Nikki. That’s it.

The State has photos of the two parties (separately) here. Ben Smith uncovers (or is emailed) evidence that Folks worked for Haley a bit in 2008. Haley, for her part, says there is no truth to the blog post, in a statement:

I have been 100% faithful to my husband throughout our 13 years of marriage.  This claim against me is categorically and totally false.
