You need to listen to the interview. It is really interesting and I am surprised that you are so gullible to believe the polls like that. There are so many examples when they have been wrong. This election season they are completely unreliable.
When Harry Truman was running for president in September he was down 9-20 points in the polls. And those were classic polls with the same methodology as today.
the problem here is that you do not know how to win. Just when you think you have it figured out, you are wrong!
If we were in the horse and buggy days, you would say that you would love to believe in cars but you just don’t see it because too many people are driving horse and buggies.
“Gullible.” Dang, i left out gullible.
I like that much better than “naive.”
But Truman decided to take the election directly to the people and he traveled the country giving unscripted rallies, just like Trump is doing today. Only Truman rode the rails on a pretty much non-stop "whistle stop" tour. The know-it-all media were just confounded that everywhere Truman went, thousands of people showed up to hear him. Towards the end, they started getting worried but it was too late. Truman won that election pretty handily.
