Pretty #catseye galaxy from zooniverse:

Eh - Biden is in a deny-polling mode. He's disbelieving the data, it's exasperating.

I know it's numerically small (but so are wins), but this is hard to read as other an undecided shift.

(538 aggregate pre/post debate)

14% of their respondents thought Biden has better mental sharpness required for the job (vs either Trump or neither candidate), a precipitous decline from the already low place he was before the debate.

Pre-post changes like this are not to be ignored.

But there’s polling directly answering the key question.

Note that this same sample is also one of the better recent ones in terms of Biden’s chances in the election.

Should we ignore what real people are saying they want from Biden?

The post-debate change in this question from the Post-ABC News poll is staggering. It’s no wonder it also found a majority of Democrats want Biden to step aside.
