Stuttering and Biden. He deals with it just fine.

I stutter, so what I say is based on experience. First off, there are no personality or behavior traits for stutterers. Stuttering doesn’t indicate anything else about a person. It is in part clearly genetic. Also, stutterers have differences in their temporal cortexes compared to normal speakers. Basically, we’ve learn to route around it, often quite successfully.

The stuttering sequence in A Fish Called Wanda was the first time I had a belly laugh at my own stuttering. I thank them for it. In it, John Cleese has to get the name of a hotel from Michael Palin who has the most horrendous stuttering block ever, and finally has to write the name down. Then, he says the name perfectly, without stuttering. This had me on the floor laughing the first time I saw it because this really does happen. (Palin’s father stuttered, that’s why he could do it so well. The touchstone of humor can indeed be pain.)

Stuttering and maintaining fluency

Even if a stutterer is currently fluent, they are always monitoring their speech a few words ahead to determine if they might stutter. If so, then they change what they are going to say. Sometimes they stutter on a word then instantly change to another less-stutterable word.
