Verb. Usually as "to primary." To propose a challenger candidate against an incumbent politician during the primary and then do everything you can to insure the neophyte challenger is victorious over the incumbent. Thus, the incumbent becomes a regular citizen again and is free to pursue the rest of his or her political ambitions overtly bought out as a lobbyist or Washington attorney. This is the tool of last resort when a politician no longer represents the interests of his or her constituency, but of a special interest or heavy-hitting contributor that overshadows the will of the people back home.
I promise to primary any politician who votes against Social Security, Medicare, or Veterans' Benefits.
