Look at the beginning of the debate. Joe is sharp, he can put his sentences together, he's not fumbling over any words or making gaffes, and he's making valid points (if you're a lunatic liberal that is).
Fast forward 90 minutes later, he seems so lost. Just out of it, can't string the right words together, saying some truly off the wall shit, and just plain old tired, even though he had been resting for the past week.
If you watched Joepedo's town hall, you saw the EXACT same thing. Sharp, quick, and crisp answers in the beginning, but by the end just an absolute trainwreck.
No different in the first debate as well. He came out much stronger than where he ended,and just looked gone by the finish.
He's being pumped full of something that lasts 60-90 minutes, no doubt in my mind anymore
