Meh, I’ve heard the same thing about Trump. And Bush made me cringe EVERY TIME he went off teleprompter.
Then again, my brain IS Swiss cheese. Injury, not age.
Bush just sounded like every oilfield guy/gal I have ever met from Plano Texas. Be the speaker oil worker to PhD Geophysicist, they all sound the same in their syntax, word use & mannerisms! I never had any problem with it.
