I've always just assumed he is an "I-am-what-I-am-and-I-talk-the-way-I talk" kind of guy. I could be wrong (I know), but I tend to think the speech "issue" may be genuine for him; but because he's local, maybe he hasn't had anyone on his back, telling him to polish up his speech. And even if he has, maybe he's gone with the "I-am-what-I-what-I-am" thing. I'd guess he's plenty intelligent and maybe "not into" some of the more "superficial" things that shouldn't matter when it comes to doing a good job or being intelligent. Maybe he has a little fun with his reputation for speech "issues" when it comes to names - or maybe he's lazy about being more careful with names (as opposed to words that matter more and relate more to his work). (???) Or maybe he tries to turn what can be a draining speech issue (maybe to him, sometimes to those listening to him) into something that has a lighter side??) In other words, I kind of suspect he's figured out how to turn what could have been a bigger problem for some people into something he won't let be a big problem, and even may have a little fun with. Those are my guesses.
