The Elections Clause of the U.S. Constitution (Article I, Section 4, Clause 1) confers upon the states the initial and principal authority to administer "the times, places and manner" of congressional elections within their jurisdictions. As a result of this decentralized authority, states vary in how they administer such elections. At the same time, the Elections Clause provides Congress with the power to "make or alter" rules regulating congressional elections, which the Supreme Court has described as an "override" authority. Under that authority, Congress has enacted statutes, such as the Help America Vote Act of 2002 and the National Voter Registration Act of 1993, discussed below, that regulate aspects of congressional elections. For presidential elections, Article II, Section 1, Clause 4 of the Constitution provides that Congress may determine the "time" of choosing presidential electors and the day the electors shall cast their votes.
The Constitution does not provide Congress with general regulatory authority over state and local elections but does grant Congress regulatory authority in specific contexts. For instance, the Spending Clause of the Constitution (Article I, Section 8, Clause 1) authorizes Congress to condition the receipt of federal funds for state or local elections on compliance with federal requirements. The Fifteenth Amendment prohibits the denial or abridgement of the right to vote based on race or color and provides Congress with the authority to enforce the Amendment through legislation. Invoking that authority in 1965, Congress enacted the Voting Rights Act to achieve the Fifteenth Amendment's goal of bringing "an end to the denial of the right to vote based on race."
This In Focus provides an overview of the legal framework for congressional authority over elections with lists and brief descriptions of key constitutional provisions and federal statutes. In some instances, as identified below, Supreme Court and lower court decisions have significantly shaped the contours and applicability of laws enacted by Congress.

• Election Day Statutes establish Election Day, for the House of Representatives, as the first Tuesday following the first Monday in November in even-numbered years; for the Senate, on the same day as the next House election that precedes the expiration of a Senator's term; and for states to choose presidential electors, as the Tuesday following the first Monday in November every four years.
• In Watson v. Republican National Committee (2026), the Supreme Court held that the Election Day statutes do not require ballots to be received by Election Day.
• Select Federal Criminal Statutes prohibit noncitizens from voting in federal elections; make it unlawful to conspire to intimidate anyone who is voting; impose penalties on anyone who by force willfully injures or intimidates any person from voting, campaigning, or serving as a poll watcher or election official; and prohibit intimidation to interfere with an individual's right to vote.

• In a series of decisions, the Supreme Court has invalidated several FECA provisions under the First Amendment, including the FECA ban on corporate and labor union independent expenditures in Citizens United v. FEC (2010) and the FECA aggregate contribution limits in McCutcheon v. FEC (2014).
• Most recently, in National Republican Senatorial Committee v. FEC (2026), the Supreme Court invalidated the FECA limits on a political party's campaign spending in coordination with candidates.
• The Help America Vote Act (HAVA) establishes requirements for state administration of federal elections, including relating to the removal of registrants from federal election voter rolls, and authorizes federal funding; establishes the Election Assistance Commission (EAC); provides the Attorney General with certain enforcement authorities; and, as amended by the Confirmation of Congressional Observer Access Act of 2024 (COCOA), requires states to permit congressional election observers access to observe the administration of federal elections.
• The National Voter Registration Act (NVRA), also known as "Motor Voter," requires states to provide for mail-in voter registration and to establish voter registration procedures for eligible citizens at motor vehicle departments and at certain other state agencies; sets forth requirements for states in maintaining their voter rolls; provides criminal penalties for intimidating any person for registering or voting, or defrauding the residents of a state of a fair and impartial election; provides the Attorney General with enforcement authority; and establishes a private right of action for persons aggrieved by violations to file lawsuits in federal court.

• The Voting Rights Act (VRA) prohibits states and localities from applying discriminatory procedures in voting based on race, color, or membership in certain language minority groups; requires bilingual election materials in certain jurisdictions; authorizes the Department of Justice to appoint, and federal courts to order, election observers; criminalizes several acts, including fraudulent voting and voting more than once in the same election; and provides the Attorney General with enforcement authority.
• Although most courts have assumed that the VRA's Section 2 prohibition on discriminatory procedures establishes a private right of action, the U.S. Court of Appeals for the Eighth Circuit ruled in 2023 that Section 2 does not confer such a right.
• In Shelby County v. Holder (2013), the Supreme Court invalidated the VRA's coverage formula that identified states and localities that were required to obtain federal government approval before implementing a change to a voting law or practice, known as preclearance.
• In Brnovich v. Democratic National Committee (2021), the Supreme Court interpreted Section 2 of the VRA in the context of state election administration laws, holding that Section 2 requires voting to be "'equally open' to minority and non-minority groups alike" and establishing "certain guideposts" for courts to consider in ascertaining violations.
• In Louisiana v. Callais (2026), the Supreme Court significantly narrowed the circumstances under which a racial vote dilution challenge to a redistricting map can be made under Section 2 of the VRA, holding that violations require evidence supporting "a strong inference" that a state intentionally created a redistricting map that provides minority voters with less opportunity to elect preferred candidates.
