Top: Marvel’s latest teaser for… something happening this year, with Loki apparently running for President.
Bottom: Glen Orbik’s cover for DC’s 2000 LEX 2000 one-shot, back when Lex was running for office. (And he won! Oh, DC, you with your crazy ideas.)
Lex winning the presidency is right up there with Joe Casey’s pacifist Superman as far as forward-thinking ideas with that franchise. It was the best victory Lex could score over Superman: the people elected him. They chose Lex Luthor. So much could have been done with that and, from what I saw, very little was, unfortunately. (But, I could be wrong.)
Nah, it was a pretty wasted opportunity – it really did offer a lot of potential for returning Superman to a place of anti-authority-yet-still-morally-superior that spoke to his early days, but that was pretty much abandoned even before the first arc of Superman/Batman literally blew up the premise by having Lex break out his battlesuit and be revealed to be injecting himself with liquid kryptonite.
