The U.S. government helps regulate several key areas, including the economy, national elections, and the judiciary, but it does not directly regulate local government. Economy:
The federal government regulates the economy through economic regulation, which includes oversight of industries such as telecommunications, transportation, and finance to ensure fair competition and consumer protection. Economic regulation also involves reviewing regulations to improve resource allocation and address societal benefits, such as controlling inflation and monitoring wage and price stability

. National Elections:
While state governments primarily administer elections, the federal government plays an important regulatory role in federal elections. This includes enforcing voting rights protections under laws like the Voting Rights Act, prosecuting federal election crimes, and setting uniform federal election standards such as Election Day. Federal agencies and Congress also oversee election laws and ensure compliance with federal statutes, although federal involvement is traditionally limited to these areas to respect state control over elections

. Judiciary:
The federal judiciary, comprising the Supreme Court and lower federal courts, exercises judicial power by interpreting the U.S. Constitution and federal laws. It resolves disputes between the executive and legislative branches and ensures laws and regulations comply with constitutional principles

. Local Government:
Local governments (counties, municipalities, townships, etc.) operate under state authority and are not directly regulated by the federal government. The federal system shares sovereignty with state and local governments, each having its own powers and responsibilities as defined by the Constitution

. In summary, the U.S. government regulates the economy through federal agencies and economic policies, oversees national elections primarily through enforcement and legal frameworks, and operates a judiciary that interprets laws and the Constitution. Local governments are primarily regulated by state governments, not the federal government.
