South Carolina Gov. Mark Sanford's admission of an extramarital affair has knocked him out of the running for the GOP nomination for President in 2012. The question now is, whom has his withdrawal from the field most helped?

Answer: Former Arkansas Gov. Mike Huckabee.

When Sanford resigns -- as he will most assuredly have to do -- the state's Lieutenant Governor, Andre Bauer, will ascend to the governorship.

Bauer, already an announced candidate for the GOP nomination next year, would become an incumbent running for election to a full term of his own in 2010.
