What are some example of states protecting citizens against abuses of power by the national government?

States can protect citizens against abuses of power by the national government through various measures, such as implementing laws that safeguard civil liberties, like state-level privacy protections. They can also establish independent oversight bodies to monitor federal actions and ensure accountability. Additionally, state courts can serve as venues for challenging federal policies that infringe on individual rights, allowing citizens to seek justice at a local level. Finally, states can refuse to enforce certain Federal Laws deemed unconstitutional or unjust, asserting their sovereignty.
