Grover Cleveland came back after just one term, and many others tried to do this. Martin Van Buren ran as a third-party candidate eight years after leaving office. What's the longest gap we can come up with?
My thought was that Jerry Brown could run and win in 1976, then lose in 1980 as Carter did. And then (say) his career goes not so differently from IOTL, except that it culminates in his running for the Democratic nomination in 2020, winning it, then going on to beat Trump. Maybe Brown returns as California governor four years later so he's still in office in 2020, and he somehow becomes the voice of COVID policy criticism, and Joe Biden isn't running for whatever reason. Maybe a narrative of "and he'll be a transitional figure for sure, as the only person in the race who cannot run in 2024" takes hold too, something something.
If he pulled it off, that would make his first and second terms (as the 39th president and the 46th president) separated by 40 years...
