Why Election Myths Spread — and Why They Matter
Beliefs about how U.S. elections operate are often shaped by social media, partisan messaging, and genuine confusion about a decentralized system that varies considerably from state to state. When those beliefs are inaccurate, they can erode public trust in democratic institutions or discourage people from participating in the process altogether.
The following myth-and-fact pairs address some of the most widely circulated misconceptions, grounded in what election law, academic research, and government records actually show. For a closer look at one contested area of election policy, see our article on how voter ID laws work and what research says about their effects.
Myth
Voter fraud is rampant in U.S. elections and routinely changes outcomes.
Fact
Documented cases of voter fraud are extremely rare, and large-scale, outcome-altering fraud has not been substantiated in modern federal elections.
Multiple investigations — including those conducted after the 2016 and 2020 elections — found no credible evidence of widespread, coordinated fraud. The Heritage Foundation's election fraud database, which is frequently cited by those concerned about the issue, contains roughly 1,300 proven instances across decades of elections covering billions of votes cast. Prosecutions are rarer still. Election experts note that the decentralized, multi-layered nature of U.S. election administration — with oversight spread across thousands of local jurisdictions — makes systemic fraud extremely difficult to execute undetected.
Myth
Mail-in ballots are not verified and are easy to fraudulently submit on someone else's behalf.
Fact
Mail-in ballots go through signature verification, ballot tracking, and other security steps before being counted.
Every state that allows mail-in voting requires some form of identity verification — most commonly a signature match against the voter's registration record. Many states also require a witness signature or notarization. Ballots are tracked through the postal system, and voters in most states can monitor whether their ballot was received and accepted. Election officials are trained to flag discrepancies. Returning a mail ballot in someone else's name is a federal crime punishable by fines and imprisonment.
Myth
Non-citizens vote in large numbers in U.S. federal elections.
Fact
Non-citizen voting in federal elections is illegal and evidence of it occurring at any significant scale is not supported by the available data.
Voting in federal elections while not a U.S. citizen is a federal offense that can result in deportation and criminal prosecution. Studies that have claimed to find high rates of non-citizen voting have been widely criticized by political scientists for methodological flaws, including errors caused by imprecise database matching. Post-election audits, including those conducted by Republican and Democratic officials alike, have not surfaced evidence of non-citizens participating in meaningful numbers.
Myth
The candidate who wins the most votes nationwide automatically becomes president.
Fact
The presidency is decided by the Electoral College, not the national popular vote.
Each state is allocated a number of electors equal to its total congressional representation (House seats plus two senators). In most states, all electors go to whichever candidate wins that state's popular vote. A candidate must reach 270 electoral votes to win. This means it is possible — and has happened multiple times in U.S. history — for a candidate to win the presidency while receiving fewer total votes nationally. Maine and Nebraska use a congressional-district method that can split their electoral votes.
Myth
If you're not registered weeks before Election Day, you cannot vote.
Fact
More than 20 states and Washington, D.C. allow voters to register on or close to Election Day.
Registration deadlines vary significantly by state. Some states require registration 30 days before an election, while others — including Colorado, Wisconsin, and California — permit same-day registration at the polls or during early voting. North Dakota has no voter registration requirement at all. Voters should verify the rules in their specific state well before any election, as deadlines and procedures change. The National Conference of State Legislatures maintains current registration deadline information by state.
Myth
Voting machines are connected to the internet and can be hacked remotely to change results.
Fact
Most certified voting systems used in U.S. elections are air-gapped — meaning they are not connected to the internet during voting or tabulation.
The vast majority of voting equipment used in American elections operates on closed, standalone systems without internet connectivity. Paper ballot backups exist in most jurisdictions, and post-election audits — including risk-limiting audits — are increasingly standard practice. The Cybersecurity and Infrastructure Security Agency (CISA), a federal agency, has repeatedly described U.S. election infrastructure as secure and has found no evidence of vote-changing cyberattacks in recent elections. That said, experts acknowledge that no system is perfectly immune to all threats, which is why layered physical and procedural security measures remain important.
Understanding the Broader Election System
Several of the myths above share a common root: most Americans have limited exposure to the actual mechanics of election administration. The United States has no single national election authority. Instead, responsibility is distributed across more than 8,000 county and municipal jurisdictions, each operating under the laws of its state. That complexity makes the system harder to manipulate at scale — but also harder for the public to understand.

Local election jurisdictions in the U.S.
The U.S. Election Assistance Commission estimates there are more than 8,000 election jurisdictions across the country, each with its own administrative procedures.
~1,300
Proven voter fraud cases documented over decades
The Heritage Foundation's election fraud database — one of the most frequently cited resources on the topic — documents roughly 1,300 proven instances across decades of U.S. elections.
270
Electoral votes needed to win the presidency
Of the 538 total electoral votes allocated across all states and D.C., a presidential candidate must secure at least 270 to win the White House.
The Electoral College adds another layer of complexity often misunderstood by voters. Winning the presidency requires earning 270 electoral votes — a state-by-state competition that can produce a winner who did not receive the most individual votes nationwide. Our explainer on the Electoral College and why your state's size changes everything breaks down how that system works in practice.
Primary elections, which often receive less attention, can be just as consequential as general elections. Primary elections vs. general elections examines why many races are effectively decided before most voters tune in. And for context on participation patterns, midterm elections and why voter turnout tends to collapse explores the structural reasons turnout drops sharply in non-presidential years.
