If he ran again in 2020... well, it would be pretty fitting considering he's done his whole career path twice, but it's pretty crazy that it's not absolutely out of the question for someone who was on the national stage at the same time as Carter and Reagan to still be there.
His 1976 campaign by contrast was oddly similar to his current persona, a kind of center-left, pragmatic technocrat. The conventional wisdom seems to be that he only lost because Carter figured out quicker how to campaign in the new primary system (1976 was the first year that primaries rather than state conventions dominated) and racked up a bunch of early delegates.
