Though America has had quite a few great presidents, iconic presidents are much rarer. Icons appear only in hindsight and are created in a very specific fashion. First, one party will hail the president as great, while the other claims he has wrecked the country. Then the opposing faction realizes the president wasn’t that bad, and reckons with his policies and broader influence, changing its own policies in the process. And finally, both parties fight to claim the president as their own, that they are his true heirs.
