You're talking to someone who stutters. If Biden was having significant, noticeable issues speaking in public, I don't think he ought to be running the free world. There are plenty of other individuals who are smart, intelligent, and have no communication issues. If you have a handle on your stutter, by all means, but if you're being intellectually honest--Biden is slipping. I can't say if he truly has a stutter, to me it seems closer to cognitive decline. Perhaps I'm wrong about that, but I don't believe I've seen a single clip where it seemed like he has ever had one, but perhaps that is a kudos to his ability to master his speech.
