2026 Election Picture for Wisconsin
Wisconsin's 2026 primary was held on August 11, 2026. Wisconsin does not have a U.S. Senate seat up for election in 2026 — its senators' class isn't on this cycle's ballot. All 8 of Wisconsin's U.S. House seats are on the ballot in 2026, since House terms are two years. The general election is November 3, 2026.
2026 is a midterm election year — it falls in the middle of the presidential term, so there is no presidential race on Wisconsin's 2026 ballot. Every U.S. House seat nationwide is on the ballot every two years, and roughly a third of U.S. Senate seats — whichever class is next in rotation — are up in every congressional election, midterm or presidential.

Senate Class Breakdown
U.S. Senators serve staggered 6-year terms split into three classes, so a state's two Senate seats usually aren't on the ballot in the same year. Wisconsin's two Senate seats are staggered across different classes.
The staggered system dates to the Constitution's framers, who wanted the Senate to change gradually rather than all at once — unlike the House, where every seat turns over every two years. Roughly one-third of the Senate's 100 seats (whichever class is next up) is on the ballot in any given election year, which is why only some states have a Senate race in any particular cycle.
- Ron Johnson is Class 3 — next up for election in 2028.
- Tammy Baldwin is Class 1 — next up for election in 2030.
