Polls have been remarkably accurate in the last few election cycles.
The “polls are wrong” talking point is a convenient way for politicians to ignore the will of the people. Trump has done this for a long time, and recently Biden has taken up this practice to pretend that the “Real Americans” think he is fit to be president for another 4 years.
So please don’t repeat this talking point, or at least read a bit into historical accuracy of polls before you declare them bullshit.
Polls have a margin of error and election results have generally been within the 80% confidence interval 80% of the time.
It is true that when there are less polls (like in special elections) it’s harder to get an understanding of the state of the race.
