The campaign has sent out a notice of a major endorsement announcement at 1 p.m. Tuesday at the South Carolina Statehouse. Here’s my logic that suggests it’s Sanford:

• It’s got to be someone of prominence in South Carolina or the press conference would be in Tampa.

• There are no other major endorsements coming out of South Carolina that mean anything to anyone outside of South Carolina.

• Some delusional prognosticators have suggested that a Sanford endorsement would help in Florida.

• Oh, and Sanford endorsed him in 2000, but kept his mouth shut through the state primaries this year.

UPDATED: It’s not Sanford. It’s Joe Wilson.
