I have been thinking about polling. I admit upfront that I don't really know how it works except that the pollster calls up a bunch of people, asks them questions, and tallies up the responses. I was wondering how they handle someone like me who, when a pollster calls, immediately hangs up no matter whether the poll is about politics or potato chips. I guess they just cross me off the list, and keep calling until the reach the bottom of the list. That kind of takes out of the equation a certain kind of person. The question is is a hanger-upper more likely to vote for Trump or Biden, or for sour cream or barbeque chips. Maybe polls erroneously showed Biden leading Trump in certain jurisdictions because Biden voters were less likely to hang up on the pollster than Trump voters, or, as has been suggested before, Trump voters lied and said they were voting for Biden because they didn't want to admit the were voting for Trump. I guess this would be more prevalent in political polls. Who is going to lie about what kind of potato chips they prefer? So how do you account for the hanger-uppers, if at all? You can't really poll the hanger-uppers because they hang up.
