I think you’re going about it the wrong way. Biden became a senator, then vice president, then the president of the most powerful country in the world. If anything, the takeaway here should be that someone with a severe stutter was able to overcome it and achieve things 99.99999999% of people cannot. Biden will be super unhappy otherwise. Also Most people are making of his old age, which I agree. We need a younger and more dynamic president, not ancient candidates like Biden or trump.
