The Red, White and Blue Fund, the super PAC supporting former Pennsylvania Senator Rick Santorum's bid for president, announced a new $600,000 ad buy in South Carolina today. The group, formed in December, had previously made an ad buy of $190,000 in the Palmetto state. This latest buy brings RWB Fund's spending total to just under $800,000 in this crucial primary state.

The organization will continue to air their ad titled "Pride," a 30-second ad already on the airwaves in South Carolina media markets. The Red, White and Blue fund has indicated that they plan to release additional ads soon.

Santorum was the last of the six leading GOP candidates to get aid from a super PAC. The independent expenditure organization spent $537,000 on ads supporting the former Pennsylvania senator in Iowa, ahead of his second place finish.
