They won't.
Despite what you hear on lemmy, the average american is not living in some kind of fascist hellscape. They are working a pretty decent job for a wage that pays their bills, and everything for them is more or less the same as it was under Biden. They are unhappy with the increased cost of things - but they aren't even close to "riot in the streets".
Instead, their strategy will be:
- ignore the federal government until the next election
- vote in opposition politicians in city and state elections in the meantime
Legally, the states can't make laws that contradict federal law. But as the case of marijuana legalization has shown, the federal government is very hesitant to push back on laws passed by states with broad popular appeal. So in the meantime, we'll likely see moves by the states to become more autonomous, and will see more anti-Trump politicians make names for themselves and get ready for the national stage.
