My picks:
Best Fictional President:
Josiah "Jed" Bartlett from "The West Wing."
HOW has Martin Sheen never won an Oscar or Emmy?
But he has to win here, "The West Wing" was one of the best American Dramas ever, both on the count of Emmy awards and nominations--I think it was at least nominated for Best Drama every year of it's 7-year, 170+ episode run, and won a few times there--and was simply a great show...
If you haven't seen it, watch it, and watch it over again (though you'll probably like it more if you lean Left than Right, but still, there are some good Republican characters, like Ainsley Hayes and Arnold Vinick and Glen Allen Walken...)
Sheen as President Bartlet really cemented an already-great cast--
His President is sort of a hybrid of FDR, JFK, and Reagan...
FDR's illness and some of the same ideas...
JFK's charisma and the fact both are Catholics and from blue-blood New England families...
And Reagan's look, his oratory ability, and the fact both were shot but not fatally...
At least, that was my take.
Anyway, great series, and the best-ever fictional President, too many great moments to list! :)
But for the Most Entertaining...
I'll cheat, and just say:
