“To the right of Ivan the Terrible/ Attila the Hun/ Genghis Khan”

There is a political right and a political far right. To be politically “to the right of Ivan the Terrible” (or “to the right of Attila the Hun” or “to the right of Genghis Khan”) means to be very far to the right. The three warrior kings did not necessarily share the same “politically right” philosophy of government. The phrase means that these famous people are extreme (and certainly not moderate), and a person to their right would be even more extreme.
 
The phrase is often associated with Arizona Republican Senator Barry Goldwater (1909-1998), but it is not clear when he first used it. The “Ivan the Terrible” version is cited in print from 1961, the “Genghis Khan” version from 1965, and the “Attila the Hun” version from 1969.
