Pollsters always over poll Democrats. Below is a video showing the Real Clear Politics average polling in swing states in the 2020 election. For an example, all the way through the summer, Biden led Trump in Ohio except for on election when Trump led by one point. Trump won Ohio by 8.
In Wisconsin, Biden led Trump in RCP polling the entire campaign, and on election day was favored to win by 6.7 points. Biden won Wisconsin by less than a point.
The discussion regarding the 2020 polling starts at the 2:40 mark in the video at the link. (The first couple of minutes is on current polling and you might find that interesting as well.)

As I said, Pollsters always over-poll Democrats. Of course, we don’t need to ignore the polling, but we have to remember the Democrats plan is to demoralize conservatives and discourage new voters from going to the polls.
Also, part of the reason for polls constantly showing Democrats in the lead is so no one will be surprise when they cheat enough to win. For instance, they have shown GOP senators losing in states even when Trump is in the lead by several points. Do you really believe large numbers of GOP voters will vote for Trump and then vote for the Democrat Senator? I don’t.
Conservatives have to vote in large numbers to beat the margin of fraud. The GOP has to have poll watchers and attorneys in place in all the democrat strongholds to thwart the cheating. And conservatives need to volunteer to be poll-watchers, so as many eyes as possible are watching on election night.
