Funny that this was in response to me and not the above poster that claimed that something happened in 2016 that made them no longer reliable.
Additionally, I suspect you don’t really know what you are talking about because the issue you point out is not a statistical issue, but that they are just not a good measurement to begin with. Which isn’t even a good point either because they do a pretty good job of consistently getting pretty close. In the last election the mean error was only about 4.3 and they didn’t seem to favor either side.
Polls would be ok if the sample was peefectly random. However it is never fully random, and in practice they always overrepresent politically active people and underrepresent the poor.
What are you talking about? Polls are not valid statistics, they are riddled with biases that can’t be eliminated.
