The polls are absolute shit. You can draw a little bit of a conclusion that if Biden went up by 2 points, that probably means that wherever the real answer is, it might not be crazy to think it went up by somewhere from 1 to 3 points because of something that happened. That part may be worth being slightly happy about. But whether that real answer is +2 like they say, or -10, or +20, modern polls actually can't tell you, and all these people that are telling you they can, are lying. In my opinion.
Source: I looked through the methodology they actually use for this polling and found it to be dogshit, and then looked up a few polls for recent elections and found that the poll differed from the actual result of the election by an average of 16 percentage points.
