I agree. Plus, I never figured out what this “great orator” stuff was all about. He has a halting and somewhat confused delivery and a nasal, hectoring tone of voice, harldly the stuff of Pericles. Or even MLK, who did have a smooth and dynamic oratorical style.
I guess maybe you have to be a devotee to understand it...
I admit I can’t listen to him speaking! It’s not the delivery, which is simply ordinary, but the content. I expect those who consider him a great orator are seeing it the opposite way - they love the content, so they impute greatness to the delivery.
