Preemption

Explanation:

Federalism

This is simply known as a form of constitutional setup where power is shared between a central government government and a sub divisional governments called states.

Preemption

This is commonly defined as the right of a federal law or regulation to preclude enforcement of a state or local law or regulation. It happens only if federal law or regulation takes precedence over state or local law or when state or local government touch on a federal field.

The Supremacy Clause stated the Constitution and federal laws are the supreme law of the land. In the advent or occurrence of conflict between federal and state law, the federal law will control and the state law is rendered void.

There are 2 primary instances of preemption. They include:

1) Where federal law expressly preempts state or local law, and

2) Where preemption is implied.
