Remember how some Republicans have expressed concern about what past experience tells us is the distinct possibility of Mark Sanford’s campaign imploding on itself?

Shaking my head. So much.

Former South Carolina Gov. Mark Sanford must appear in court two days after running for a vacant congressional seat to answer a complaint that he trespassed at his ex-wife’s home, according to court documents acquired by The Associated Press on Tuesday.The complaint says Jenny Sanford confronted Sanford leaving her Sullivans Island home on Feb. 3 by a rear door, using his cell phone for a flashlight. Her attorney filed the complaint the next day and Jenny Sanford confirmed Tuesday the documents are authentic.

The couple’s 2010 divorce settlement says neither may enter the other’s home without permission. Mark Sanford lives about a 20-minute drive away in downtown Charleston.

Pro tip: When you are about to run in a special election in which you are trying to stage a recovery from a mind-boggling display of poor judgment, avoid further displays of poor judgment at all costs.

We already knew that the Colbert Busch camp was going to be hammering Team Sanford on everything that was wrong with the “Appalachian Trail”-governorship debacle, but something like this might provide further ammunition for that line of attack. The incident happened after he consulted on his campaign with his ex-wife in January, but before the primary and then the runoff at the beginning of April — I can’t even begin to speculate about what possible excuse Sanford might have for having been there, but I think it’s safe to say they were hoping this wouldn’t become public. No comment from Team Sanford yet.
