Well, there are varying opinions on that. I agree with you somewhat, but many that "voted for that" have said otherwise and either 1) didn't ever hear about said document or 2) actively dismissed it as "fake news" or 3) believed the president when he said he'd never heard of it and it wouldn't be his agenda.
Trump himself, and his spokespeople, all publicly denied that they had anything to do with Project 2025 ahead of the election. It was a laughable lie, the only people who believed it were apparently the media, who reported it as fact.
