I'd turn this around on the demented Hollywood minstrels.
An actor, by definition, is a person whose livelihood is based solely on their ability to assume a false persona and recites words and ideas scripted by other people. The last person I would ever want in a position of leadership is an actor, because actors are nothing more than living puppets.
Therefore, to suggest that a politician is a "bad actor" would be the ultimate complement: it means that that person is genuine and has a mind or his own.
It's sad that so few people--particularly in this country--have the capacity to understand that entertainers and performers are nothing more than that: purveyors of fantasy. People should enjoy them for their on-screen make-believe role-playing, but ignore them in the real world.
(By contrast, when I first traveled to the then-recently-fallen Soviet Union back in 1991, Yuri Gagarin was still hailed by the Russian people as a national hero. That was their idea of a "celebrity." Thirty years after his pioneering achievement, you could still go to any street vendor selling watches, t-shirts, and other "pop icon" memorabilia and find Gagarin's name and likeness on the merchandise. I'd wager that 90+% of our citizens couldn't even name the first American in space, let alone tell you who Gagarin was and how he earned his place in world history.)
Alan Shephard right? :-) But seriously the Razzies aren't given out by actors or Hollywood at all. It's a group of wannabee film critics.
