All you have to do is look at the rallies. People are not excited by Hillary, they don’t show up. People show up at Trump rallies by a power of 10 compared to Hillary’s rallies. There is simply no way any poll is correct. They aren’t polling average Americans.
Bernie had lots of people at his rallies. He still lost.
Hillary’s supporters aren’t interested in hearing her speak. They just are confidsnt she will deliver their benefits.
