Apparently, Trump supporters weren’t looking at any of the polls. All of them had Biden winning, I mean all of them. Some poll by more, some by less, but all had Biden winning.

https://www.cnn.com/election/2020/exit-polls/president/national-resultsFor Trump supporters to believe the election was stolen, means none of them paid any attention to what was happening in the general election campaign or to the polls. They must have gone into a cocoon and blocked the real world completely out. The writing was on the wall for everyone to see, if they could read that is.
Blocking the real world of politics out, going into a cocoon isn’t just done by Trump supporters. I don’t think Trump nor his supporters ever realized how much Trump was disliked outside of Republican circles or should I say the Republican cocoon. That also was written on the wall for all to see from the first day Trump’s presidency to his last to even to today.
