I watched it live. It was like watching a middle school student who'd won a competition to take part in the debate. In the second debate he looked desperate. And what was that creepy sex pest act he did? I think sitting on a chair while your opponent's speaking is far preferable. He acted like a petulant child, claiming the moderators of being biased against him, and was forced into a humiliating faux apology. His attempts to goad Hillary into reacting to his Bill Clinton sexual assault accusations failed completely and gave her the opportunity to take the moral high ground. How could you possible characterise that debate as anything other than an obvious defeat? Even the Republican commentators they had on the news after the debate couldn't claim that he'd performed well. I'm pretty sure even Donald Trump himself knew that he'd fucked it up, hence why he was all over Twitter straight away trying to deflect attention from it.
