Anyone who is an eligible, registered voter for U.S. federal elections can vote in the midterm elections; there is no special “midterm-only” voter category. The same basic rules that apply in a presidential year apply in midterms.

Basic eligibility

To vote in U.S. midterm elections, you generally must:

  • Be a U.S. citizen (some places may let certain non‑citizens vote in local races only, but not in federal midterm contests like Congress).
  • Meet your state’s residency requirements (usually living in the state for a defined period before Election Day).
  • Be 18 years old on or before Election Day; many states let you register earlier if you’ll be 18 by then.
  • Be properly registered to vote by your state’s deadline (North Dakota is the only state that does not require formal voter registration).

These rules apply whether the election is a presidential year or a midterm year, because midterms are just the regularly scheduled elections held halfway through a president’s term.

Who typically cannot vote

Most midterm voting restrictions are the same as in any other federal election:

  • Non‑citizens , including lawful permanent residents, cannot vote in federal midterm races.
  • Some people with felony convictions or who are currently incarcerated lose voting rights, depending on state law.
  • In some states, certain people under court‑declared mental incapacity may be restricted from voting.
  • U.S. citizens living in territories (like Puerto Rico or Guam) cannot vote for president in the general election, but they may have local or territorial races on their ballots; federal House delegate races are separate.

Because rules on criminal records and capacity vary significantly, checking your specific state’s election office is critical.

Midterms, primaries, and party rules

Midterm general elections (for Congress and many state offices) are open to every eligible voter in the jurisdiction, regardless of party registration. However, midterm primaries —where parties pick their nominees—can have extra rules:

  • Some states run open primaries , where any registered voter can choose which party’s primary to vote in.
  • Others have closed primaries , where you can only vote in the primary of the party you’re registered with.
  • Semi‑closed or partially open systems allow unaffiliated voters or restrict “party crossover” differently by state.

Those primary rules affect how you vote in midterm season, but they don’t change who is fundamentally eligible as a voter.

How to know if you can vote

To quickly check whether you can vote in the next midterm:

  1. Confirm that you are a U.S. citizen and will be 18+ by Election Day.
  1. Look up your state or local election office website to verify residency, registration status, and any state‑specific rules about criminal records or other restrictions.
  1. Check your state’s party primary rules (open, closed, etc.) if you plan to vote in midterm primaries as well as the general election.

In short, if you are a U.S. citizen, at least 18 by Election Day, meet residency rules, and are properly registered under your state’s law, you can vote in midterm elections just like in a presidential year.
