Isn't there a already a movement to create "Obama Day?" There will never be a Reagan Day, a JFK Day, or a FDR Day for that matter. It is undeniable Reagan is worshipped by conservatives, as the Kennedys (The old ones, not Caroline) are worshipped by the left. But Obama will be a god if he is sucessful, and will be undoubtfully surpass Reagan and JFK in Fandom, and actually, already has.
Ahem...
