The one thing I learned in statistics is how easy it is to manipulate polls. Not only what question is asked, but the order of the questions matter. The polls report that Biden's approval rating is way higher than every American believes it to be. All that means to me is somehow they manipulated the questioning. Even if they simply asked "Do you approve of Joe Biden?" did they ask that after a leading question that could skew the answer? For example if the pollsters asked "Do you believe we would be better off if Donald Trump had been elected president again" would lead the democrats answering to respond differently. Instead of telling the pollsters if they approved of Joe Biden, they would be responding to the question the previous question raises, "Would I rather have Joe Biden as president now rather than President Trump?"
For a poll that is obviously misleading, I want see the actual questions and such factors as how they conducted the polls and the demographics of the persons conducting the questioning. All those factors can be used to skew the results.
