Ah, but the federal Constitution is the “one ring” that binds them all. If you have a state law that someone feels doesn’t fit with the principals of the US Constitution, the USSC gets to review it in the light of the US constitution, and the basic rights embodied in the US Constitution trump the state’s laws, if they are out of sync. That was one of the conditions of federalism.
