There's a reason not to put too much faith in polls. Here's an example from the Harvard Youth Poll, which surveys only people age 18-29:
In the first question, 4% of the respondents say they are transgender or non-binary. In the very next question, a tenth of those who said they are, now say they aren't. An even larger number suddenly prefer not to say even though they had just said.
This is not something complicated about the world, where you might be unsure of the nuances. It's a question about yourself, and within the space of a few seconds a large number of respondents flipped for no apparent reason.
Also, the first two questions suggest that 2% of the respondents consider themselves non-binary. But in the third question 0% say they are non-binary. Come on.
Here's another:
This is why I'm skeptical of some recent polls showing that Biden has lost significant support among the young or the Black or whatever. In the right-hand column, where we eliminate all the "would not vote" folks, 37% say they'll vote for Trump compared to 28% who voted for him in 2020. Does anyone really believe this? I don't.
