Tonight, Trump:
—Complained about having to hold a microphone, threatening to “knock the hell out of” the staff and calling them “stupid”
—Went on an unintelligible rant about “the weave” and said he has a “very fertile brain”
—Acknowledged that more and more people are calling him “cognitively impaired”
—Spoke to countless empty seats by the end of the rally as many supporters left early
