The Constitution grants states primary authority to regulate elections while allowing Congress to intervene, and federal amendments protect voting rights against discrimination.

States’ Authority Over Elections

Article I, Section 4, Clause 1, known as the Elections Clause, gives state legislatures the power to determine the times, places, and manner of holding elections for Senators and Representatives. This means states are responsible for the procedural aspects of elections, such as voter registration, polling locations, and ballot design, unless Congress enacts laws to modify these rules.

The Constitution explicitly allows Congress to override state regulations, but the president has no authority over election rules .

Courts have emphasized that states may regulate elections to ensure fairness and efficiency, but they cannot infringe on fundamental voting rights 

Federal Protections and Voting Rights

The Constitution also includes amendments that protect voting rights and limit state power to discriminate:

• 15th Amendment (1870): Prohibits denying the right to vote based on race, color, or previous condition of servitude 
• 19th Amendment (1920): Grants women the right to vote 
• 24th Amendment (1964): Eliminates poll taxes in federal elections 
• 26th Amendment (1971): Lowers the voting age to 18 
  Federal legislation, such as the Voting Rights Act of 1965, enforces these protections by preventing discriminatory practices at the state and local levels, including literacy tests and other barriers usconstitution.net+1. While states manage the mechanics of elections, federal law ensures that these powers are exercised without violating

Key Takeaways

• States have primary responsibility for election administration under the Elections Clause.
• Congress can regulate or override state election rules to protect voting rights.
• Constitutional amendments and federal laws prevent states from discriminating in voting.
• State constitutions and laws provide detailed frameworks for fair elections, including redistricting and voter protections.
  This balance reflects the Constitution’s design to empower states in election management while ensuring that fundamental voting rights are protected at the federal level.
