My older son swears Scrotus is medicated. He says he doesn't know if he's addicted to opioids or benzos and pops them himself or if someone is slipping them to him to keep him from totally losing his shit live on TV.
IDK, but he certainly does appear as if he's on something. The slurry speech, the little 'blip' when he loses of his train of thought then recovers it, even the fact that he appears to have to work to focus his vision at times.
I'm not completely finger pointing. It wouldn't be the first time a POTUS was medicated. It's pretty well accepted these days that JFK at times was on pretty heavy pain meds for his back and that he and Jackie took 'energy' injections from some doctor that were probably 'more than vitamins'.
