Every time the states push back and remind him of the limits of his powers, Trump acquiesces. And then the states either go back to sleep on their duties (cleaning up their own voter rolls) or run roughshod over their citizens’ rights (in trying to get a handle on the Coronavirus).
BTW, I don’t see that as a failing in Trump. But the states are clearly more accustomed to Democrat Presidents who use the power of the Federal government to compel them to execute their mandates. Otherwise they can be capricuous.
What is he supposed to do? Would you have him send in the military? That would go over big, since the bulk of the Republicans in Congress wouldn't back him on that decision. He's damned if he does, and damned if he doesn't.
