First off, old men usually aren't very animated. More to the point, The Simpsons brand of humor isn't very political, so it's probably impossible to do good good episode of the show in which having a specific President (or ex-President) be a major guest star. Besides, the only living ex-President who has had a post-Presidency that would be worth alluding to in an episode of that show would be Jimmy Carter.
Except, as I alluded to, they made an entire episode about HW Bush, and it is literally my favorite episode of the entire show. And not just me, it’s generally considered a classic.
Back in the day, at least, they were absolutely capable of top notch political satire. The ONLY thing that could have made that episode would have been Bush voicing himself.
That episode came about not because of politics, but a sassy comment Bush made about the show. They literally could have made essentially the same show using any other celebrity, political or not, who had the good sense to prefer
The Waltons to
The Simpsons. It was satirizing a celebrity, not a politician.
