In fiction, and/or non-fiction has an A.I. ever been in politics?

A book called The Raft, boss got it me for Christmas. You have to read it to believe it; wild ride

Wasn’t that the idea of the 1980s TV character “Max Headroom”?

Nope, not politics. Too bad.

In “Inside Job”, they created a robot to secretly replace the president.

That sounds like Philip K Dick territory. I’m sure he’s written at least one story that includes an AI president.

Cool Q!
It will be fun to track down what jellies mention.

You could go back to Isaac Asimov’s I ROBOT. It tracked the fictional rise of robots from clunky children’s toys to a creation that ran for and won president of the world.
