Obama’s style of talking does not wear well.
He has many irritating vocal mannerisms and they become more and more obvious, especially when he’s not doing a prepared speech.
I can hardly bear to listen to him.
You hit on a real problem Obama has with the public. The more they see and hear him, the less they like him. It was one of the reasons he limped across the finish line with Hillary in the primaries. A few more weeks and a few more primaries and Hillary would have been the nominee.
