Of course...

"Idiocracy"

We will not go quietly into the night! We will not vanish without a fight! We're going to live on! We're going to survive! Today we celebrate our Independence Day!

Kinda floored he hasn’t been mentioned yet, so I’ll throw him in the mix.

Morgan Freeman, obviously.

Anyone. Literally any movie president would be better than what we have. I'd take Bill Pullman, Harrison Ford, Jack Nicholson from Mars attacks, anyone.

The versions of historical american presidents seen in the american mythology. The world could use a president as great as the George Washington patriotic Americans think he was.

Nixon’s head on a robot body.

Morgan Freeman and no one can say different. I can sleep on a cloud of his voice

For USA? Roland Crane, since his only act shown in his office was getting offed by missile strike.

either of them

When he wasn't trying to engage in his favorite pastime of killing and vilifying Superman, Lex Luthor was a pretty good President all things considered.

Film: Dave (1993).

Everyone should watch this movie at least once.

Dave!

The Federation president is probably passable. Though Star Trek really doesn't show how the Federation government is structured probably because they don't want to lean too much into the socialist undertones in case they get canceled (like actually canceled) for it.

In general or in comparison?

Henry Hayes from Stargate SG-1

President Kamacho is sorta like the president we have now if that's what you're into.

Alexander Purchinov.

Dave

Vasyl Petrovych Holoborodko?

Chauncey Gardner

Jack Ryan from the books

In one Simpsons episode Cletus was a president, I'd think he would do his job well.

David Palmer.

Nayak (2001)

Richard Splett

President Merkin Muffley.

Literally any of them.

Stephen Colbert. Though iirc in the marvel universe he won the popular vote but lost the EC vote to Obama.

He still would be a good president.

Volodymyr Zelenskyj, while not perfect, has proven he can both play and do the job.
