This is good stuff mikeh. Thanks for the videos. I know the internet polls are unscientific and too easily manipulated by bots, but wasn't it interesting they all indicated an overwhelming support for Trump. I thought that was just too easily dismissed by the "purists".
It would be interesting to see how many of the major polls in the "too close to call" category fell within their calculated margin of error or confidence interval and think they did OK because of it.. The problem there lies within the fact that almost all of them had Clinton in the lead, which tells me there was something wrong with their basic assumptions or definition of "likely voter". Even so, if the final outcome of vote percentage fell within the margin of error, it was still a major fail.
On my own part, I knew 20 years ago that I was never going to vote for another Clinton and I think a significant number of actual voters were in the same boat. So for us, we were tired of the derision and political argument trolls that have been so pervasive, especially for the last 8 years.
Living in a "swing State" my land line rang constantly. I never answered any of the calls. Never answered any calls on my cell from numbers I did not recognize. The fact of the matter is, that I would have lied anyway if I had been cornered. This is the new reality the pollsters have been facing for the last 4 to 6 election cycles and they either don't know how to fix it or are unwilling to face reality. Another thing is, very few of the pollsters are basically honest in framing their questions and seek a foregone conclusion.
So essentially they are getting the lions share of opinion for their polls from a biased population or they are getting the answers they are interested in seeking. None of them reached the "never Clinton" voters who eventually voted for Trump. (Perhaps with the exception of the LA Times) Apparently there were enough of them for Trump to carry the States he was never expected to win. That's why I believe they were all so far off the mark and their is no solace for any of them for falling within the "margin of error".
