What kind of President would Jimmy Carter have been had he really won in 1976? I'm not too concerned with the PoD here -- maybe Ford makes a debate gaffe, maybe there's a recount in Ohio* -- just looking at the Presidency itself.
*OOC: TTL, Ford wins Ohio and Hawaii, the former by less than 1,000 votes, giving him 270 ECVs (even as he loses the popular vote)
