I would vote for Tom Bombadil.
I'm sorry, but this thread just feels like a jab to stir up political tension. Yes, we know a presidential election is coming up...
However,
Eomer brings up a very interesting point about Gandalf with which I very much agree - Gandalf would not support even a pseudo-democratic-republic thingy...I mean, what was one of his big missions? To restore a wise king to the throne of Gondor. Conveniently a blood heir and benevolent.
(As for some things that have been said, I'm not sure we're discussing "modern US politics" or the "modern US media"...one may present the other and define the other in many ways, but there's a lot more to anything/anyone beyond a face... But no, I am not discussing politics! Noooo, did I take the bait??)
