True, I think Sorkin went a bit too far in creating the Bartlet character... oh, he's a former governor and a former U.S. congressman. And a Nobel prize winner in economics. And a direct descendant of a signer of the Declaration of Independence. Perhaps he did land on the moon too? Bartlet's background reminded me of Buckaroo Banzai... physicist, neurosurgeon, rock star, and race car driver.
Despite Bartlet's far-fetched curriculum vitae it's still a great character though.

However, he would have worked just as well by making him a "normal" economist who hasn't won the Nobel prize and by dropping the signer of the Declaration of Independence thing.
But maybe Sorkin wanted to have a total fantasy president.
