Actually the no land line problem really affects the polling of the black voter. I would venture to say that blacks have a lower percentage of land lines proportionally than whites. If I was a pollster this would drive me crazy.
Secondly, it was of registered not likely voters.
Lastly, what are the demographics of the people you polled?
Yes, it’s obviously a VERY flawed poll.
Using only landlines omits many Hillary voters (ethnic, young). And that’s compounded by not weighting the results to the demographica of the state.
If they told us the demos of their respondents one could adjust for it and make some use of the poll.
I thought the ‘one question’ nature of the poll was very interesting though. Such a method could show the intensity of support for a candidate.
