The WI-04 district, encompassing Milwaukee and its suburbs, maintains a strong Democratic partisan lean reflected in its D+26 Cook Partisan Voting Index and consistent election results. Incumbent Democrat Gwen Moore, first elected in 2004, secured roughly 75% of the vote in 2024, and the seat carries a Solid D rating from multiple forecasters ahead of the November 2026 general election. With primaries scheduled for August 11, 2026, and filing deadlines already passed, multiple Democratic contenders face limited Republican opposition in a district where structural factors favor one party. Trader consensus pricing at 93.5% for Democrats captures this entrenched advantage, though late developments such as candidate scandals, court-ordered redistricting shifts, or an unusually strong national Republican wave could still alter outcomes before ballots are cast.
