What in the heck are they talking about, he was always like that, they just choose to ignore it.
He could never do the impromptu very well. Trump does it too well. Never a vocalized pause. Obama is nothing but stammering and ahs and ohs and aAAAs. He was always a terrible speaker. Just a puppet. An empty suit in an empty chair.
Now his voice is shrill and his ideas coarse and mundane. His venues are away from any place where there would be a hint of resistance.
He should never have served a second term.
