Mary Amonitti of Hilton Head, S.C., asks a question to Republican presidential candidate, Texas Gov. Rick Perry during a campaign stop at the Hilton Head Diner, Friday, Jan. 13, 2012, in Hilton Head, S.C.

After Perry lost an important South Carolina backer, he's changed the focus of his attacks to Obama rather than Mitt Romney on the campaign trail today at a diner in Hilton Head. NBC's Mark Murray breaks down where all the campaign money is being spent in the Palmetto state.

The South Carolina Republican primary is Jan. 21.  It will take 1,144 delegates to win the nomination at the Republican national convention this summer. So far, Perry has collected no delegates.
