Everything You Need to Know About the Midterm Elections

What are midterms, why do they matter, and what exactly you should expect.

Updated: March 23, 2026


2026 is a big year. And not just because of the Olympics! 2026 is a midterm election year, and every vote counts! In a recent civic engagement poll, many young people said they planned to take part in the upcoming elections. However, a portion still didn’t realize there was an election this year, which shows why midterms need more buzz and attention.

While critical to our democracy, midterm elections often don’t receive all the buzz and media attention that surrounds a presidential election. This guide equips you with the tools and resources needed to strengthen your civic engagement muscle in 2026.

What are midterm elections?

Great question! As the name implies, midterms happen in the middle. Midterms, or midterm elections, take place two years into a President’s four-year term.

We are in the midst of the midterm primary election season. Primary elections — which take place in the spring and summer leading up to general elections — determine which candidates will represent each political party on the ballot. These primary elections begin as early as March 3, 2026 and run through late summer and early fall, with dates varying by state.

The general election during the midterm cycle is held on the Tuesday after the first Monday in November: this year on Tuesday, November 3, 2026.

Who and what is on the ballot?

Midterm elections are crucial for electing representatives for Congress, as well as state and local governments.

Congress is composed of two bodies: the Senate and House of Representatives. The Senate has 100 senators; the House has 435 representatives. Senators serve six-year terms and representatives serve two-year terms.

In 2026:

All 435 seats in the U.S. House of Representatives are up for election.

35 of the 100 Senate seats are up for election (33 regular Class II seats plus 2 special elections).

State governors, attorneys general, and many legislative seats are also on ballots in many states — about 39 gubernatorial elections including 36 states and 3 territories.

So in addition to Congress, many statewide and local offices and ballot measures will vary by location.

Why do midterms matter?

We get it. Midterm elections don’t feel as “flashy” as presidential elections. But trust us — they are just as important. Midterm elections allow citizens to vote on the issues and leaders that matter most. By using your vote during a midterm election, you can help shape the makeup of Congress and state governments, influencing policies and budgets for years to come.

The results can change which party controls the House and Senate, which affects which bills become laws and how federal agencies operate. Midterms also often influence state policy on things like education, health care, and voting rules.

How do you prepare for midterm elections?

↪ Register to vote

If you haven’t already, now is the time to register. Check your registration status and register before your state’s deadline — many are in October 2026, but some states allow same-day registration.

↪ Make a voting plan

Decide whether you’ll vote in person, by mail, or during early voting (which in many states begins in mid-October 2026).

If voting by mail, request and return your absentee ballot with time to spare.

Locate your polling place and know what identification you may need.

↪ Know what’s on your ballot

Before casting a vote, research your races and ballot measures. Look up candidates’ platforms, watch debates or forums, and review nonpartisan voter guides to understand who and what you’re voting on.

The general election for the 2026 midterms will be held on Tuesday, November 3, 2026.

Check your state election website for the specific date where you live.

Why your voice matters.

Using your vote during the midterm elections means you help choose officials who represent your views on issues like student debt, climate change, reproductive rights, and more. Midterms set the stage for how the next two years of governance will unfold — and they help shape the political landscape going into the next presidential election.

Let’s Do This!

As we approach the 2026 midterms, keep this in mind: Every voice — and every vote — matters. And together, our votes have the collective power to demand that our democracy works for all!
