He's already made history so if his Presidency ended now he'd still be remembered above Bush and Clinton.

He has to get a second term. No modern day President has been deemed great after only one term. If he fails to be re-elected in four years time he will be dubbed a failure.

If Obama gives us eight years of what he says he's going to give us then he'll probably go down as one the greatest of all presidents.

EDIT: Zee make a good point. Obabm did jump the queue and is a very inexperienced politician especially regarding forign affairs. This will be his biggest stumbling block but unlike Bush he possesses more than a couple of braincells so I think he'll be Ok in the end.
