Has there been a general election loser coming back and get the party nomination again?

In recent history, I can't recall any candidate who loses in the general election comes back and becomes the nominee again. Hillary Clinton, John Kerry, John McCain, Mitten all didn't seek another chance. Usually, the party that lost would do some soul searching for why they lost and find a new candidate.

Is TFG defying history again? I can't help but think it's a cult more and more each day. I guess the whole stolen election thing kept him as the center of attention and never gave a chance for people to do the soul searching needed. Other candidate usually stay quiet and let the party do it's thing.
