I remember working a temp job at a polling call center and although I was just doing grunt work of calling people, it was clearly obvious they were doing polls to hear what they wanted. There was only 1 survey out of maybe 200 that was what I would consider unbiased and didn't have any leading questions or pre-picked answers.
You would screen out people in the beginning of the survey that were obviously not interested in whoever candidate you were calling in regards to, and more often than not the survey itself would have leading questions to get the answers they want so they can take the results and be like, "See our Candidate is winning!!!" - yet they only called people and did the survey with those who were already willing to vote for said candidate.
Polls are literally circle jerking people who were voting democrat and those regarding republican candidate were always negative.
It also could be that the particular call center I was working out of only had contracts with Democratic parties/PACS but from my time there it was clear that polls are a racket.
Yet I think as the public discourse among this group continues to grow in sophistication it will develop a more nuanced worldview and will assert its power with greater wisdom.
A big part of the issue is that people have different definitions for all the various social classes, so it's hard to compare things correctly.
