Permanent campaign
The Permanent Campaign is a theory of political science conceived by Patrick Caddell, then a young pollster for U.S. President Jimmy Carter, who wrote a memo on December 10, 1976 entitled "Initial Working Paper on Political Strategy".
"Essentially," Caddell wrote, "it is my thesis governing with public approval requires a continuing political campaign." In the case of Bill Clinton, sometimes referred to as the "permanent election".
