Polls are crap
It’s a little bit notable how they change over time, but mostly it is just a bunch of poor methodology noise
But, I do feel it’s relevant to point out that even in polling land Biden has been gaining for the last few weeks and it’s notable which media outlets are pretending it is the opposite of that (like severely the opposite) and to wonder why that is
There are about 5 polls that actually matter in this election.
Pennsylvania (whoever wins this will likely take all), Michigan, Arizona, Wisconsin, and Nevada.
Georgia, North Carolina, and Minnesota might matter but I don’t see much chance of them voting Blue, Blue, or Red respectively.
Wherever you are, just go vote to make the House as blue as you can. Mark down the democratic nominee for president while you’re there.
And even in those places, Trump supporters are known for not wanting to admit to pollsters that they support him, so they’re not super reliable
On the other hand, Biden supporters are known for not answering phone calls from unknown numbers which makes them even less reliable.
Yeah, maybe it evens out, maybe not.
That is one of 10 various reasons why the polls are not reliable in various directions
