I managed to watch it all this afternoon, Trump started ok, but soon descended into shouting/talking over both Clinton and the moderator, often waffling and repeating the same words, it was clear he was thinking while he was speaking a lot of the time, which is a very worrying should he be in any sort of diplomatic situation. Debates are often the best indication of someone's leadership credentials and he clearly hasnt got what it takes to lead and to be in a position to negotiate anything with any great effect, I wouldnt say he's a fool, but he's clearly not that bright and was obviously lying quite a bit. Clinton was polished, many moons ago before she was a Clinton she was a lawyer and it shows, she beat him up in the argument repeatedly and had a good grasp of the facts most of the time, however she is just unlikable, the bit where Trump spoke a whole load of guff should have been a moment where she destroyed him, but she said wow listen to what you just heard, was a little bit creepy and not done with any style, just an air of superiority that so many hate her for, at least she didnt cough or collapse and her answer about stamina was probably her best moment.
Not that it will make any difference, most of those that watched or are bothered by the debate have already decided who they are voting for. Trump being what he is, he admitted to being a racist, tax dodging, elitist doesnt seem to bother most of the red necked bigots that are supporting him.
One thing it did was make me feel glad for Corbyn, I'm not his biggest fan but it showed we have a real choice in this country these days in comparison to the states.
