(screen shot of a guest at McCain's BBQ. Video here)Political pundits almost pathologically believe they have greater influence than they really do. Case in point, Talking Points Memo's editor and publisher and chief blogger Josh Marshal has been trying to promote the use of the phrase "ride the swing" as a metaphor for the case when "a reporter who has gotten way too cozy with a politician and has had their supposed objectivity affected" (original explanation here). The phrase refers to a posh BBQ that McCain hosted at one of his Arizona ranches where journalists were treated to a very comfy social experience that bordered on bribery (click on "video here" below the pic). As far as I can tell, Marshal is the primary pusher of the phrase and its most frequent user (a couple other examples here and here).
I suspect Marshal's linguistic campaign will fail. Attempts by a single person to explicitly promote the use of a new metaphor are rarely successful. This is not how language works. Successful new coinages are generally adopted less self-consciously. The process is not well understood, but examples like Marshal's are few and far between. Additionally, there are already several good metaphors for related frames, such as "drank the cool-aid" (which has equally obscure origins involving jungles and religious cults). Not sure we need a new one just for journalists.
(HT to my colleague CC for bringing this to my attention. At first, we had no clue what this metaphor referred to, and as such we literally couldn't understand what it was meant to evoke. CC did some blogger detective work and discovered its origin).
