South Carolina senator Lindsey Graham has launched a new political action committee for “testing the waters” for a presidential run in 2016. The Republican, in his third term, has started Security Through Strength, a PAC that bluntly describes itself as a group to “fund the infrastructure and operations allowing Graham to travel the country, listen to Americans, and gauge support for a potential presidential candidacy.”

The PAC appears to have a website and at least two staff members, including Graham’s campaign manager Scott Farmer and treasurer Thad Westbrook.
