Just a few weeks ago, it looked like Mark Sanford was headed to defeat in South Carolina’s First Congressional District. He had made a notable misstep, which caused the National Republican Campaign Committee to pull resources from the race. Sen. Rand Paul (R-KY) and FreedomWorks, a grassroots-driven organization, stepped into fill the void, with the former providing vocal support and the latter activists to educate voters in the district.

Sanford wound up defeating his Democratic opponent by a healthy margin, providing Paul, who is thought to be candidate for the GOP’s presidential nomination in 2016, and FreedomWorks with notch on their belt against the Republican political establishment.

Fresh off this victory, FreedomWorks has now set its sights on another South Carolina race that could shake-up the Republican Party.
