Look at the history of the award. Mostly they've done a good job, although in recent years it's been more and more debatable. Some years NO award was given.
Can I think of someone? No. I'm sure there is someone deserving of it... or maybe not - as I noted sometimes no award was given. But Gore definitely doesn't deserve the friggin' Peace prize. At least with Carter it made sense.
And, for the record, I don't think Reagan deserved it either (as others are arguing). I liked what he did, but his means were not in the spirit of the Peace Prize.
