The presidential campaign of John McCain just sent a release across the wire announcing that “former POW Col. Jack Van Loan, USAF (Ret.), Attorney General Henry McMaster, and Adjutant General Stan Spears will unveil John McCain’s first television ad to air in South Carolina on Thursday, December 20.”

The video will be played at 1:30 p.m. at the campaign’s headquarters in Columbia.  No word on when or where it will air in the state.

For McCain, who is catching up in Iowa and New Hampshire, the Palmetto State is once again shaping up to be make-or-break. But first he has to win NH, and that will be no easy task.
