Guys. I am not a quant person but even I know that pushing a sub sample of a larger phone poll from early in June with a 0.8% response rate, where no one who ignores unlabeled numbers on their cellphone responded, tells you nothing about the electorate. Stop letting bad polls drive your politics.
I don't think that correction fixes all the errors in your description "a sub sample of a larger phone poll from early in June with a 0.8% response rate, where no one who ignores unlabeled numbers on their cellphone responded". Where do you see this is a phone poll with a 0.8% response rate?
