You can quite obviously hear him say that he’s a terrible person for the job.

He’s an entertainer, he needs to be popular with his audience, and thus he needs to disguise negative feedback with humor.

If he spoke plainly, he would have said to the guy wanting him to run for president “you barely know me, you just heard like 5 sentences you like and you’re already wanting me for president. That’s totally stupid, but it’s understandable because these 5 sentences are already better than anything you heard from Trump. I’m not even a good candidate and you’d still take me just so you don’t have to have Trump. So no, please actually try to elect someone that’d be good at the job, don’t force me to do it who would suck. Look at what I’m doing now, I can’t even plainly tell you what I think, my desire for approval is so high. Be happy that I only use my charm for random humoric nonsense, if I’d use my charm for personal gain I’d basically be Trump, he also was mainly an entertainer.”

So yeah, while he doesn’t answer it directly, he does his best of trying to answer it based on the constraints that his person is being placed under.
