*In case you’re around a Secret Service agent barking the word “renegade” into his or her wrist, it’s safe to assume that Sen. Barack Obama is somewhere close by.
On Sunday, the agency revealed to the Washington Post a list of code names it has given to its high-profile clients. Obama was christened "Renegade," while his Democratic rival, Hillary Clinton, is known as “Evergreen,” her husband Bill Clinton’s tag is “Eagle,” and Eagle’s former vice-president, Al Gore, is named "Sawhorse."
Secret service agents bestow nicknames as a way to communicate with each other without having to utter the person’s name as he or she engages in daily activities. Although officials say monikers are chosen without particular reference to a politician’s characteristics, Obama’s “Renegade" may be viewed by some as a nod to his status as the lone black candidate running for president.
As for former presidents, Jimmy Carter, a former Sunday school teacher, was known as “Deacon”; Ronald Reagan was referred to as "Rawhide," and George Bush Sr. was "Timberwolf."
The secret service refers to your current president as “Tumbler.”
