When Americans vote for president, members of Congress, or other federal offices, they are participating in a national election. But the federal government does not operate one nationwide election system.
Instead, elections are administered primarily by state and local governments, operating under a combination of federal and state laws.
Congress has authority to establish important election requirements. Federal agencies enforce voting rights laws, oversee campaign finance, provide technical assistance, and help protect election infrastructure. Courts resolve disputes about how election laws apply.
This division of responsibility is part of the American system of federalism, in which governmental powers are shared between national and state authorities.
Understanding who controls elections requires separating three questions: who makes the rules, who conducts the voting, and who determines whether those rules have been followed.
What Does the Constitution Say About Elections?
The Constitution establishes the basic division of election authority.
Article I, Section 4, commonly called the Elections Clause, gives states responsibility for establishing the times, places, and manner of elections for the U.S. House of Representatives and Senate. It also gives Congress authority to make or change regulations governing those congressional elections, subject to a narrow constitutional exception concerning the places of choosing senators.
This means states generally establish election procedures unless applicable federal law provides otherwise.
Presidential elections operate under a somewhat different constitutional framework. Article II gives each state authority to appoint presidential electors in the manner directed by its legislature, subject to constitutional limitations and federal law. Congress determines the time for choosing electors and the day on which they vote.
Constitutional amendments also protect voting rights. For example, the Fifteenth Amendment prohibits denying or abridging voting rights because of race, color, or previous condition of servitude. The Nineteenth Amendment protects against voting discrimination based on sex, and the Twenty-Sixth Amendment protects voting rights for citizens who are at least 18 years old against denial or abridgment on account of age.
These provisions establish national limits on how governments may regulate voting.
What Do State Governments Control?
States are the primary authorities responsible for organizing federal elections.
Within federal constitutional and statutory requirements, state laws determine many of the procedures voters encounter.
These may include:
- Voter registration procedures and deadlines.
- Rules for early voting and absentee or mail-in voting.
- Voter identification requirements.
- Polling-place administration.
- Voting equipment certification and use.
- Ballot processing and counting procedures.
- Recounts, audits, and certification of results.
State legislatures enact election laws, while state election agencies and local officials implement them.
In many states, the secretary of state serves as the chief election official. Other states assign major election responsibilities to election boards, commissions, or different offices.
State constitutions and courts also affect election administration. State election laws must comply with applicable state constitutional requirements as well as federal law.
Because states have substantial authority, voting procedures can differ significantly across the country even when voters are selecting candidates for the same federal offices.
What Do Local Election Officials Do?
Although state governments establish much of the legal framework, local election officials carry out most of the practical work.
Depending on the state, elections may be administered by counties, cities, towns, townships, or local election boards.
Local officials maintain voter registration records, prepare polling places, recruit and train election workers, distribute ballots, operate voting equipment, and process votes.
They also secure election materials, maintain records, report results, and conduct the local canvass or other required verification procedures.
For example, a county election office may be responsible for preparing ballots for several congressional and legislative districts, operating early voting locations, processing absentee ballots, and reporting results to the state.
In another state, those responsibilities may belong primarily to municipal clerks or local election boards.
Local officials must follow applicable laws and regulations. They generally cannot change eligibility requirements, discard valid votes, or establish their own counting rules contrary to law.
What Authority Does Congress Have?
Congress can establish federal election requirements through legislation enacted under its constitutional powers.
For congressional elections, the Elections Clause provides broad authority to regulate election procedures and override conflicting state rules within its scope.
Congress has used its powers to establish nationwide protections and administrative requirements.
Examples include the Voting Rights Act of 1965, the National Voter Registration Act of 1993, and the Help America Vote Act of 2002.
These laws address matters such as voting discrimination, voter registration procedures, provisional ballots, election equipment standards, and election administration.
Congress has also established the nationwide date for regular federal general elections and enacted laws governing presidential electoral vote procedures.
However, congressional authority is not unlimited. Federal election legislation must be supported by constitutional powers and comply with constitutional protections.
Congress does not ordinarily operate polling places, maintain local voter lists, or count individual ballots.
Does the President Control Federal Elections?
The president does not have general authority to personally administer federal elections or decide election results.
The executive branch carries out federal laws, and the president oversees executive agencies within the limits established by the Constitution and federal statutes.
A president may propose election legislation, sign or veto bills, appoint officials to federal positions where authorized, and direct lawful executive-branch activities.
Presidential executive orders can direct executive agencies within the president's legal authority. They cannot independently rewrite the Constitution, override valid federal statutes, or grant the president powers reserved to states, Congress, or the courts.
For example, a president cannot simply issue an order declaring that a particular candidate won an election or directing state officials to disregard legally cast ballots.
Changes to federal election requirements may require congressional legislation, state action, or judicial decisions, depending on the subject.
What Does the Election Assistance Commission Do?
The U.S. Election Assistance Commission, commonly called the EAC, was established by the Help America Vote Act of 2002.
Its responsibilities include helping election officials improve election administration, maintaining voluntary voting system guidelines, supporting voting equipment testing and certification programs, and providing information about election practices.
The EAC also administers certain federal election assistance funding programs and collects information about election administration.
Its voting system guidelines help establish technical expectations for equipment reliability, security, accessibility, and performance.
However, the EAC does not conduct federal elections nationwide or directly count votes.
States retain responsibility for determining which voting systems may be used under their laws, subject to applicable federal requirements.
What Does the Federal Election Commission Do?
The Federal Election Commission, or FEC, regulates federal campaign finance under federal law.
Its work concerns how money is raised, spent, and disclosed in campaigns for president, the U.S. Senate, and the U.S. House of Representatives.
The FEC administers and enforces applicable federal campaign finance requirements, including reporting and disclosure rules.
It does not operate polling places, determine voter eligibility, count ballots, or certify election winners.
The distinction is important because the Election Assistance Commission and the Federal Election Commission have similar names but very different responsibilities.
The EAC focuses on election administration assistance and voting systems. The FEC focuses on federal campaign finance.
What Does the Department of Justice Do?
The U.S. Department of Justice enforces federal laws that protect voting rights and prohibit certain election-related crimes.
Its Civil Rights Division handles matters involving federal voting rights protections, including discrimination and other violations covered by applicable statutes.
The department may bring civil lawsuits to enforce federal election laws or challenge practices that violate federal protections.
Federal prosecutors may also investigate and prosecute election-related crimes within federal jurisdiction, such as certain forms of voter intimidation, election fraud, or corruption.
The Department of Justice does not ordinarily supervise routine ballot counting or replace state and local election administrators.
Its enforcement powers are defined by federal law and are subject to judicial review.
What Role Does the Department of Homeland Security Play?
The Department of Homeland Security has responsibilities involving the security of critical infrastructure, including election infrastructure.
Within the department, the Cybersecurity and Infrastructure Security Agency, known as CISA, provides cybersecurity guidance, technical assistance, threat information, and other support to election officials and infrastructure operators.
Election infrastructure can include voter registration databases, election management systems, voting-related computer networks, and systems used to report results.
CISA may help election officials identify vulnerabilities, prepare for cyberattacks, and respond to security incidents.
However, providing cybersecurity assistance is different from controlling an election.
CISA does not determine which candidates win, certify election results, or possess general authority to direct state officials to count or reject particular ballots.
What Role Do Federal and State Courts Play?
Courts resolve legal disputes involving election laws, constitutional rights, and election procedures.
A dispute may concern voter registration, district boundaries, ballot access, voting rules, recounts, or the legality of an election official's actions.
State courts interpret and apply state election laws and state constitutional requirements. Federal courts address cases involving federal statutes, the U.S. Constitution, and other matters within federal jurisdiction.
A court may order officials to comply with applicable law, correct an unlawful practice, or take other action authorized by law.
The U.S. Supreme Court may ultimately decide certain federal constitutional or statutory questions.
Courts do not ordinarily conduct elections themselves. Their role is to interpret and enforce the law when a dispute falls within their jurisdiction.
Who Controls Presidential Elections?
Presidential elections involve an additional constitutional process: the Electoral College.
Voters cast ballots in elections administered by their states. Each state appoints presidential electors according to its legally established process, subject to federal constitutional and statutory requirements.
State officials determine and certify election results under applicable law. The appointed electors then meet and cast electoral votes for president and vice president.
Congress receives and counts those electoral votes in a joint session governed by federal law.
The Electoral Count Reform Act of 2022 clarified important aspects of this process, including the limited, ministerial role of the vice president when presiding over the congressional count and the procedures for objections.
Congress's role in counting electoral votes is distinct from the state and local administration of the popular vote.
The president does not personally select the winner, and the vice president does not have unilateral authority to accept or reject electoral votes.
Can the Federal Government Override State Election Laws?
In certain circumstances, yes.
The Constitution gives Congress authority to establish rules for congressional elections, and valid federal laws can supersede conflicting state requirements.
Federal constitutional protections also limit state election practices. A state cannot enforce an election law that violates applicable constitutional rights merely because election administration is generally a state responsibility.
Federal courts may invalidate or restrict unlawful state election rules when a proper case is brought before them.
However, federal agencies and executive officials must act within powers granted by the Constitution and federal law. They cannot simply take control of state election systems because they disagree with state policies.
The legal answer depends on which federal authority is being exercised, the election involved, and the specific state requirement at issue.
Who Decides Which Voting Machines Are Used?
Voting equipment selection is generally a state and local responsibility, subject to applicable legal requirements.
States may establish certification standards, approve particular voting systems, or require specific security and accessibility features.
Local election jurisdictions may purchase equipment from systems permitted under state law.
The federal Election Assistance Commission operates a voluntary federal voting system testing and certification program. Some states incorporate federal certification into their own approval requirements, while others use different approaches.
There is no single federal agency that purchases and operates every voting machine used across the country.
Who Is Responsible if Something Goes Wrong?
Responsibility depends on the nature of the problem.
A polling-place equipment malfunction is generally handled initially by local election officials under state procedures.
A dispute over a state's voting requirements may involve state election authorities or the courts.
A suspected violation of federal voting rights law may fall within the Department of Justice's jurisdiction.
A cybersecurity incident may involve state and local election officials working with technical specialists and, where appropriate, federal agencies.
An alleged campaign finance violation may fall under the Federal Election Commission or other authorities, depending on the law involved.
Because different institutions have different responsibilities, identifying the correct authority is an important part of understanding how election problems are addressed.
Why Doesn't the United States Have One National Election System?
The decentralized structure reflects the Constitution's allocation of authority between state and federal governments.
Rather than establishing one national election office responsible for every aspect of voting, the American system assigns most election administration to states and local jurisdictions while allowing Congress to establish federal rules and protections.
This arrangement produces differences in registration deadlines, ballot formats, early voting opportunities, counting procedures, and election administration.
It also means that a problem in one jurisdiction does not automatically affect voting systems in other jurisdictions.
Decentralization does not eliminate security risks or administrative errors. It changes how election responsibilities, oversight, and responses are distributed.
The system depends on cooperation among government institutions, adherence to election laws, and procedures for reviewing disputes and verifying results.
The Bottom Line
No single person or federal agency controls every aspect of American federal elections.
States establish and administer most election procedures, while local election officials perform much of the day-to-day work of registering voters, operating polling places, counting ballots, and reporting results.
Congress establishes federal election laws within its constitutional authority. Federal agencies provide assistance, enforce specific laws, regulate campaign finance, and help protect election infrastructure. Courts resolve legal disputes and determine whether government actions comply with the law.
Presidential elections also involve state-appointed electors and a separate congressional process for counting electoral votes.
The central principle is that election authority is divided among multiple institutions, each with legally defined responsibilities and limits.
