IMO most people who are not members of the "elites" will see her performance as excessively robotic and programmed. The constant wide eyed Kewpie doll smiling , eye rolling, sneering, etc. was quite annoying. It brought to mind Al Gore's behavior in 2000.
OTOH his inability to sustain a performance over 90 minutes is a turn off for those who think the president ought to work 18 hours a day for four years. I don't share that view. A person who works that much soon suffers from exhaustion that affects judgement.
IMO the polls will give her a rather uneven bounce for a few days and then return to a very close race. pl
