I don't know why people still fall for polls, but:
"The New York Times/Siena College polls of 3,662 registered voters in Arizona, Georgia, Michigan, Nevada, Pennsylvania and Wisconsin were conducted in English and Spanish on cellular and landline telephones from Oct. 22 to Nov. 3, 2023."
I don't know how many elections in a row I have to point this out, but you cannot accurately sample and poll educated zoomers and millennials using landlines (which they don't have) or cell phones (which have major mismatches between area codes and where these groups actually vote).
If your poll tells you that 18-29 year olds are 47-46 Biden and that 30-44 year olds are 47-43 for Trump, you have flat-out fucked up the poll.
