I like FDR who managed to get America back to work after the great Depression and (albeit a bit late) committed the states to WWII.
Lincoln also represents for many people the good things about America, a man who believed in freedom for all, and who knew how to treat a vanquished foe.
Of recent vintage, I don't know, maybe Clinton but he seemed to promise more than he delivered (insert your own Lewinski joke here).
Clinton, despite his indiscretions actually did a pretty reasonable job.
I'm still regularly entertained by politics in the US. The land of the free, where the right of women to choose the method by which they have an abortion has been compromised, just to please a few nutty Catholics.
Clinton - master politician (and corrupt b'stard!) Always made the right speech and shed tears at the right time. Very effective manipulator, which is what it's all about.
Clinton was an arse - whenever he spoke he said what the audience wanted to hear - he caused enormous problems in Asia as nobody knew what his policies were - not to mention lying under oath. It has to be FDR.
I see FDR is a popular choice. The reason why I didn't vote for him was because he deliberately made unfair treaties with Britain during WWII, taking advantage of our plight so that Washington could weaken us in the post-war world.
Al Gore - well he should have been anyhow.....can't think of any others with any kind of morals I'd wish to have representing the alien nation anyhow...
