Maybe in the philosophical sense in that this is what their vote wrought, but there is absolutely no way to conclude that people wanted their institutions dismantled. The number of Americans who voted for Donald Trump was nearly identical in 2020 and 2024 once we compensate for population growth (22.4% of the population vs 22.7%). Anyone making drastic conclusions on the will of the people is just making something up whether they are conscious of that or not.
What changed is the number of people who decided they were ok with dismantling institutions. That grew by about 7 million, who voted for the opponent in 2020 but stayed home in 2024.
So perhaps the number of people who wanted institutions dismantled remained the same. But the will of the people as a whole changed sharply, mostly because of people who decided it wasn't worth the effort to oppose it.
