So I’ll say this for Trump: he had a punchy exchange on the emails that probably did him some good with his base. He also at least got a joke or two in there, which is an improvement on the perma-snarl. As far as everything else is concerned: He didn’t apologise properly for his words about women the way he *so clearly* needed to; he passed up the chance to disavow Islamophobia in favour of a riff about Muslims as fifth column; he threatened to *jail his opponent*; he was mind-bogglingly ranting and incoherent on foreign policy; seemed to admit he pays no federal income taxes; he moved around weirdly on stage between answers; he said he hadn’t spoken to his running mate about Syria and disagreed with him about it. Wall to wall ignorance and indiscipline on show. Fun for his base. Nothing that could win over a single person with doubts.
