Types of Elections in the United States

The United States holds dozens of distinct election types at the federal, state, and local levels, each governed by a different set of rules, timelines, and purposes. Understanding the structural differences between these elections matters for voters, candidates, and election administrators alike. This page covers the major categories of U.S. elections, how each functions mechanically, the scenarios in which each arises, and the criteria that determine which type applies in a given situation.

Definition and scope

An election, in the U.S. civic context, is a formal process by which eligible voters choose among candidates or decide a policy question, with the outcome carrying legal or governmental force. The Federal Election Commission (FEC) oversees federal elections — those for President, Vice President, U.S. Senate, and U.S. House of Representatives — while state and local elections fall under the jurisdiction of state election authorities and county or municipal boards.

The United States conducts elections across at least 6 distinct structural categories: primary elections, general elections, special elections, runoff elections, recall elections, and ballot measure elections (including referendums and initiatives). Each category serves a discrete civic function and operates under rules that vary across the 50 states plus the District of Columbia and U.S. territories.

How it works

Each election type follows a defined procedural sequence:

1. Primary elections narrow a field of candidates within a party or across parties before the general election. The primary elections explained page details the distinctions between open, closed, semi-closed, and top-two primary formats. Open vs. closed primaries differ most significantly in whether voters must declare party affiliation to participate.

2. General elections are the final, binding contests between nominees. In federal cycles, general elections for Congress occur every two years; presidential general elections occur every four years (presidential elections explained). Midterm elections are general elections held in the even-numbered years between presidential cycles, covering all 435 House seats and roughly one-third of Senate seats (U.S. Senate, "About Elections and Apportionment").

3. Special elections fill vacancies outside the normal election calendar. They are called by a governor or legislative authority when a seat becomes vacant through death, resignation, or removal. The procedural rules governing special elections are examined in detail at special elections explained.

4. Runoff elections are triggered when no candidate in an initial contest reaches the required vote threshold — which varies by state, but is often 50 percent plus one vote. Runoff elections explained covers the threshold mechanics and the states that mandate this format.

5. Recall elections allow voters to remove an elected official before the end of a term. As of the rules codified in state constitutions, 19 states permit gubernatorial recalls (National Conference of State Legislatures, "Recall of State Officials"). Recall elections: how they work details the signature-gathering and ballot qualification process.

6. Ballot measure elections present voters with direct legislative or constitutional questions rather than candidate choices. These include citizen initiatives, legislative referrals, and constitutional amendments. Ballot measures and referendums covers the procedural distinctions between these subtypes.

Common scenarios

The most common scenario is the federal general election cycle: a presidential general election every four years, with midterms filling the intervening even years. Every 2 years, all 435 House seats and approximately 33 or 34 Senate seats appear on general election ballots (U.S. House of Representatives, "Election Information").

A distinct scenario arises when a U.S. House or Senate member dies or resigns mid-term. In these cases, the governor of the affected state calls a special election. The timeline from vacancy to election ranges from as few as 70 days to as many as 180 days depending on state statute.

At the state and local level, primary elections for governor, state legislature, and municipal offices follow schedules set independently by each state. In California, the top-two primary system — known as the jungle primary — advances the two candidates with the most votes to the general election regardless of party affiliation (California Secretary of State, "Top-Two Primary"). This contrasts sharply with closed-primary states such as New York, where only registered party members may vote in that party's primary.

Recall elections represent a less frequent but high-profile scenario. The 2003 California gubernatorial recall and the 2012 Wisconsin gubernatorial recall are among the most prominent examples of this mechanism activating at the state level.

Decision boundaries

Distinguishing which election type applies requires examining four criteria:

• Vacancy vs. scheduled seat: A scheduled seat triggers a primary followed by a general election on the established calendar. A mid-term vacancy triggers a special election on an accelerated, non-standard timeline.
• Federal vs. state/local jurisdiction: Federal elections are governed by the U.S. Constitution (Article I, Section 4; Article II, Section 1; and the 17th Amendment), supplemented by federal statutes such as the Federal Election Campaign Act (52 U.S.C. § 30101 et seq.). State and local elections are governed primarily by state constitutions and statutes.
• Candidate contest vs. policy question: If the ballot item asks voters to choose a person, it is a candidate election. If it asks voters to approve or reject a law or constitutional amendment, it is a ballot measure election.
• Threshold requirements: When a jurisdiction requires a majority (50%+1) rather than a plurality to win, a runoff election becomes a structural possibility if no candidate clears that threshold in the initial contest. Plurality voting vs. majority voting examines how these threshold rules shape electoral outcomes.

Election administration — including which type of election is conducted and under what rules — is managed by state and local election officials operating within the framework described at election administration and oversight.
