Nah, he’s clearly worse. Saw an article on here where they broke his speech patterns down, looked at repetition, vocabulary, continuity of thought, etc. Trump seems to be going down scary fast.
It’s always been easier to listen to his speech than read it. At least with listening and watching, you can slip your own meanings into the vague patter. Reading forces you to try and parse meaning, and while there has never been much in his speeches, at least his Tweets were understandable. Now even those seem scrambled.
