The thing that makes Carter's presidency interesting to me is just how much a product of its time it was. Presidents like Biden, Nixon, or Reagan ran multiple times before winning. Obama, had he not won in '08, would probably have been a top-tier candidate for decades to come.
By contrast, the sequence of events that leads to Carter's presidency seems pretty intimately tied to him winning in the first post-Watergate election. The ideas he was running on and the image he presented were very much geared towards the moment. He was an obscure former governor from a state that was relatively unimportant at the time and somehow catapulted to the White House (where he was, arguably, in way over his head from minute one, but few politicians probably could have navigated that time very well). The Carter presidency seems like a historical oddity, like it shouldn't have even happened. The fact that '76 was so close and he was thrown out in a landslide four years later almost adds to this for me.
