a president cannot pardon or commute state crimes. most states have crimes against violence
This is especially true if the courts roll over and reverse the Impoundment Act, which is exactly what the Project 2025 author and OMB nominee is pushing for. The president would be able to bankrupt any State, any entity that relies on federal funding, regardless of the wishes of Congress.
And arguably they could just do it: ignore any court judgment, and watch Congress do nothing. We know he won't ever be impeached and removed, so it's sort of a foregone conclusion that impoundment power can be seized at any time.
