In the United States, the processes for recounts and election challenges are primarily governed by state law, reflecting the decentralized nature of election administration.

Recounts

When an election is extremely close, state statutes often dictate the conditions under which a recount occurs. In many jurisdictions, a machine recount is automatically triggered if the margin of victory falls below a specific threshold, such as 0.5 percent. County election officials are typically responsible for conducting these recounts according to state-mandated procedures.12

Election Challenges

If a candidate or campaign believes there were administrative errors or irregularities, they may pursue an election challenge. These are generally filed in state courts under rules established by state statutes.2

While states hold broad authority over these processes, federal involvement can occur if a party alleges violations of federal law or constitutional rights. A landmark example is Bush v. Gore, where the U.S. Supreme Court intervened in the 2000 presidential election, ruling that inconsistent manual recount standards violated the Equal Protection Clause of the Fourteenth Amendment. Additionally, legislative bodies retain the authority to judge the elections and returns of their own members.12
