Approval ratings might fall, but they've installed a system of nearly unchecked power, and have shown a blatant disregard for law. It's probably too late for even the base to affect change without bloodshed.
The flipside of the "states' rights" movement is that the Federal Government is much weaker: so while it's easier to strip away rights and dismantle federal institutions, it's also easier for individuals to oppose the concrete harm that'd cause by working the levers of their local government. https://plush.city/@scarlet/114355949314782873 gives a few concrete things that individuals (not even groups) can do, which might make an outsized difference.
