I'm Not Sure Who's the Rat, and Who is the Sinking Ship………

But following the discovery of a complaint filed by his ex-wife for trespassing at her home, the national GOP is pulling out all resources from his campaign:

National Republicans are pulling the plug on Mark Sanford’s suddenly besieged congressional campaign, POLITICO has learned — a potentially fatal blow to the former South Carolina governor’s dramatic comeback bid.

Blindsided by news that Sanford’s ex-wife has accused him of trespassing and concluding he has no plausible path to victory, the National Republican Congressional Committee has decided not to spend more money on Sanford’s behalf ahead of the May 7 special election.

“Mark Sanford has proven he knows what it takes to win elections. At this time, the NRCC will not be engaged in this special election,” said Andrea Bozek, an NRCC spokeswoman.

Sanford is facing Democrat Elizabeth Colbert Busch, a Clemson University administrator and sister of comedian Stephen Colbert, in a race that has grabbed the national spotlight.

The NRCC’s move comes hours after Tuesday night’s report by the Associated Press that Sanford’s ex-wife, Jenny Sanford, filed a court complaint accusing him of trespassing at her home in early February – which would be a violation of the terms of their divorce agreement.

Republicans said they were caught off guard by news of Jenny Sanford’s complaint. They worry other damaging revelations about Mark Sanford’s personal life that they aren’t aware of could come out in the coming weeks.

The calculus here is simple: The district is pretty red, and any money that they spent on Sanford now they would also have to spend in 2014 if he won, so it is better to let Colbert-Busch to have a few months in Congress, where her vote won't count.

That way you do not have Mark Sanford around your neck like a corpulent albatross.
