Did you notice that James Carville played Gov. Crittendon? LOL...I backtracked those brief shots 3 times, thinking, "It can't be...he's in another line of work!".

Then again, politics (although he's played the political role of producer or director, or script writer, maybe, rather than actor, in this analogy) is largely the art of convincing people...making them believe, as are film or stage.

Hmnnn...maybe Penn & Teller's act would be more analogous to politics. They fool people, while making them like it, for a (successful) living.
If you vote for government, you have no right to complain about what government does.
