I’m a little late, but if you watch his victory speech it’s pretty obvious (at least to me, as a lifelong stutterer). He has a noticeable block at the beginning, a big repetition toward the end, struggles with the word “who” and then skips it in the next sentence, and generally slurs through words a bit (presumably to avoid blocks). His speech patterns in general remind me of my own, like he’s clearly developed strategies to mask his stutter. [Here’s the link.](https://youtu.be/1AfNYztas2c)
