I think the people ignoring polling requests is huge. I am one of them. I have voted in every election since 1972 and was involved in Democratic politics years ago. The dishonesty of the Democrat Party has turned me against them and I am now Independent.
I refuse to answer the phone if I do not recognize the calling number.
According to pew, as few as 5% answer the phone and that’s of the people who still have a landline
I get one or two phone calls daily and it is crazy. Ring, “hello?”, pause, then hang up. If there is a pause, then drop it. Politicians are hiring people to make zillions of phone calls yet who answers the phone. Waste of time and money. Hillary is evil and people knew that a long time ago.
