How long does a congressional campaign take?

By Mert Yerekapan, maker of Midterms 2026 · Updated 2026-10-28

Usually a year or more. Serious House and Senate campaigns often start well before the filing deadline, and the intense part runs from the primary through Election Day. Challengers tend to need the most lead time. Incumbents are effectively always campaigning.

The rough timeline

Every race is different, but most follow this pattern:

Why the clock is so long

I think two things drive it. Money first: most campaigns spend a lot of time asking for it, and that can't be rushed. Second, name recognition. A new candidate starts with almost none, and voters need to see a name several times before it sticks.

Incumbents have a head start because they already have staff, donors and a public record. That's one reason challengers who start early sometimes do better.

The last 20 weeks

The final stretch is where campaigns get loud. Money goes into TV and mail, volunteers go door to door, and opponents start attacking. Debates and endorsements show up. Many strategists see this period as when undecided voters finally pay attention.

Short campaigns exist too

Special elections can compress everything into a few months. Open seats with no incumbent can also attract late entrants. Still, starting late is a handicap, not a strategy.

Feeling the compression

This is why I built Midterms 2026 around 20 turns, each representing a week before November 3. It's a free iPhone game where you start a party and spend each turn's actions and campaign money on offices, TV, rallies and citizen meetings. A full run takes well under an hour, so you can play through a whole campaign in a lunch break. What you notice fast is how little time 20 weeks really is.

What I'd do

Details vary by state and office, so check your state election office for the calendar.
