Rick Klein: “Among the ways Donald Trump is breaking with conventional politics? He’s not even really pretending that he won the debate. He is insisting that he won, of course – but he’s also complaining about the moderator, the questions, and even the microphone he used at Hofstra. (As his opponent pointed out, winners don’t complain about the equipment.) And in the debate’s aftermath, he is also adding fuel to a two-decade-old feud with a former Miss Universe whom he attacked for gaining weight. This is the Trump that the Trump campaign had been trying to disappear – and the Trump that Hillary Clinton’s campaign insists is the only true Trump to exist.”

“That’s what’s behind Clinton’s masterful strategy from Monday night: She set traps for Trump to fall into – or, rather, she pressed a whole bunch of buttons knowing that something would set him off. Clinton got the result she wanted. Trump’s reaction, meanwhile, took would could have been a partial victory or a split decision and turned it into a solid loss. The Clinton camp got a debate win, and then a parting gift.”

First Read: “Trump’s ill-advised feud with Machado fits into a pattern we’ve noticed throughout the campaign: When Trump is in a bad period like this, he makes it worse for himself by refusing to back down. Particularly in the face of poor reviews (remember the Khan fight after his convention message was panned by pundits?), Trump has a tendency to spiral downward for a few days until he’s convinced to stop lashing out or punching down. Our question is: how long does bad stretch for Trump last?”
