I think you mean "The fucking president of the united states", as the Boss so elloquently put it herself (I play a female character).
Seriously though, you (meaning the developers) could give the player character the title of "Pulsating spider christ, child of the flying spaghetti monster" and it'd be about the same to me, if the games enjoyable I don't care what my characters title is, well, within reason anyway.
You wanna cast the character as the president or prime minister or emperor, or tsar or whatever else, ok fine. You wanna cast the character as, a war criminal or dictator or something, then I might take issue.
Though to be fair I would give the person credit if they tried to make say, a historicly accurate game where you play as Stalin or something. I wouldn't play it personally, but I'd at least give credit where it's due since I'm sure pitching such a project would make the publisher piss nails and shit bricks.

OK yeah, I have no idea how the hell I came up with that in a thread about saints row of all things, I think I'm going to take that as a sign and go to bed. Goodnight everybody! *walks off*
