Absolutely certainly NOT Trump's thumbs involved in this.
Given the propensity of reasonable grammar, good spelling, multi-syllable words, and now viable Arabic inclusions, it is now perfectly clear somebody else is running his tweet feed. Someone with actual writing skills and a working brain. Not necessarily a nice person, but certainly not MAGA Dump.
Can I suggest we need a new game here: Did Trump Write That? The aim of the game is to analyse the writing and content of each Trump tweet and then offer a possible author's name. We then keep a tally of tweet counts by name, and see where this leads us. Note, this is not an attempt to analyse what the content means or react to it. It's an exercise in information analysis. Any up for this?
