in 2020 Real Clear Politics average of all polls had the following at their final predictions
Nevada - Biden +2.4 Result Biden +2.4
Wisconsin - Biden 6.6 Result Biden .7 (this was a big miss)
Pennsylvania - Biden 1.2 Result Biden 1.2
Michigan - Biden 4.2 Result Biden 2.8
Arizona - Biden .9 Result Biden .3
Florida - Biden .9 Result Trump 3.3 (this was a big miss)
So yeah, there were “some” big misses, but many others were right on the money. And where there were misses they were misses that underestimated Trumps support.
The polls that come out at the very end are the polls that are supposed to agree with the result. A lot of times when they can’t steal the vote, they lie about it until the very end. Then they come up with a story that the vote started to shift in the final days. That is crap. They are just trying to aline their polls with the vote they know is going to happen. Democrats often throw out a ridiculous poll to skew the Real Clear averages. But everything gets close on the last poll. Stealing the vote is a new thing. Its always been there in college towns and black neighborhoods. But not nearly to the extent of the 2020 election. That was a huge steal. A real Zuck and CIA job. They hired the vote stealers to steal far more votes than they manufactured before. In every state the steal was slightly different. But they did manufacture over 200,000 votes all together.
