All but one of the polls are internet polls where his supporters can vote for him as many times as they want.  The only real poll taken after the debate was conducted by CNN which gave Clinton 62% advantage over Drump.  Add his polling lies to the over fifty lies that were fact-checked during the debate.  He continues to lie now during his rallies when he tells supporters that his microphone was tampered with.  He's a pathological liar who no longer can has self control.
