What is a special election for a Senate seat?
A special election is a vote held outside the regular schedule to fill a seat that became empty before its term ended. For the Senate, that happens when a senator resigns, dies or leaves the seat for another reason. The winner serves out the rest of the term, or starts a new one, depending on the situation.
How a Senate vacancy gets filled
The 17th Amendment says that when a Senate seat opens up, the state governor must call an election to fill it. But it also lets a state's legislature authorize the governor to make a temporary appointment until the election happens.
States handle this in different ways:
- Some let the governor appoint a replacement who serves until a special election
- Some require a special election with no appointment
- The timing varies, and some states hold the vote at the next general election while others schedule it sooner
Because it's a state rule, the specifics change depending on where the seat is. If you're curious about one state, check that state's election office.
Why they appear on a midterm ballot
In 2026, 35 Senate seats are up. That's more than the usual third because special elections for unfinished terms are on the ballot too. When a special election and a regular race appear on the same day, voters in that state may see two Senate contests.
Special elections can also happen on their own dates in off years. Turnout is usually lower in those, which I think makes them unusually easy to swing.
Do they matter?
Yes, often more than you'd expect. The Senate is small, so a single seat can change who controls the chamber or the margin on close votes. A special election can shift that balance in the middle of a Congress.
They also give a read on the national mood, though one race is always a noisy signal. I wouldn't lean on any single result to predict a bigger trend.
House special elections
The House works differently. By the Constitution, governors must call a special election to fill a House vacancy. There's no appointment option, which is why you sometimes see a House seat empty for a few months.
How it shows up in the game
In my free iPhone game Midterms 2026, election night counts 35 Senate races, matching the real ballot size for 2026. You don't need to know the rules to play, but it helps to see that a Senate race isn't always a "regular" one. It's fictional, with invented parties and characters, and takes no sides.
