What are some of the ways in which the federal government regulates and shares power with the states? Compare and contrast some of the types of grants available to state and local governments

The federal government shares and regulates power with state governments by maintaining different laws in either's hands.

Explanation:

The federal government shares powers with the state governments by dividing state affairs  into two main specific lists which contains topics on which the two can make a law.

The first is the list of federal subjects on which the federal government has the sole right to make laws on, this includes law on national security, defense, army and technology related to intelligence.

There are other subjects in the concurrent and state lists on which the states have the right to make laws over and the federal government has a limited or no power on unless special circumstance arise.
