Except, no, they weren’t:
There were a couple of outliers (you can see them in the Silver graph from @SamSam’s post) but there are always a couple BS outlier polls like Rasmussen and Fox. All of the polls prior to the calls for Biden to step down were within the margin of error.
The biggest shift in polling wasn’t from the debate and wasn’t from the assassination attempt; it was from the calls for Biden to step down.
