2024 Presidential Election — Wisconsin
Source: Official 2024 General Election results — Trump +1.2 points over Harris. Wisconsin has voted for the winning presidential candidate in every election since 1988 — and was decided by less than 1 point in three of the last four elections.
Wisconsin’s Battleground History
Wisconsin has been the quintessential swing state of the modern era. It delivered its 10 electoral votes to the 2004, 2008 and 2012 Democratic nominees, then flipped to Trump by 0.7 points in 2016 — his narrowest state margin of that cycle. Biden flipped it back in 2020 by just 0.6 points. Trump won it again in 2024 by 1.2 points. No other state has been as reliably close.
The geography explains the competition. Madison and Dane County are among the most heavily Democratic urban areas in the Midwest — Dane County delivered Biden margins of over 130,000 votes in 2020. Milwaukee County adds another large Democratic reservoir. But the rest of the state — Green Bay, Racine, Oshkosh, the Fox River Valley and the vast rural north — has trended sharply Republican over the past two decades. The Milwaukee suburbs (Waukesha, Washington and Ozaukee counties, collectively known as the WOW counties) are the pivotal swing zone: once safely Republican, now more competitive as college-educated suburban voters have shifted Democratic on some races while remaining conservative on others.
| Year | Winner | Margin | EV |
|---|---|---|---|
| 2024 | Trump (R) | +1.2 | 10 |
| 2020 | Biden (D) | +0.6 | 10 |
| 2016 | Trump (R) | +0.7 | 10 |
| 2012 | Obama (D) | +6.7 | 10 |
| 2008 | Obama (D) | +13.9 | 10 |
| 2004 | Kerry (D) | +0.4 | 10 |
| 2000 | Gore (D) | +0.2 | 11 |
2026 Senate Race — Tammy Baldwin Defends
Senator Tammy Baldwin (D) is defending her seat in 2026, having first won it in 2012 and won re-election in 2018 by about 11 points. Baldwin is a consistent progressive and was one of the first openly gay senators. Her 2026 race is rated Toss-up by major forecasters — in a state that voted Republican at the presidential level in 2024, a midterm environment could cut either way.
Key dynamics for 2026: Baldwin has traditionally outrun the top of the ticket in Wisconsin, building a personal brand around constituent services and economic populism. But her progressive record on issues like Medicare for All could be a liability in a state where working-class voters have shifted right. Republicans are expected to recruit a well-funded challenger. The outcome could determine which party controls the Senate.
2026 Governor Race — Tony Evers Defends
Governor Tony Evers (D) is eligible for a third term and is expected to run again in 2026. Evers has consistently outperformed Democrats at the presidential level — he won re-election in 2022 by 3.5 points while Democrats lost the Wisconsin Senate race that cycle. His record on K-12 education funding and his veto record against a Republican-controlled legislature have been central to his political identity.
The Republican field for governor in 2026 is not yet set, but several figures from the party's Trump-aligned wing are expected to contest the primary. Full Wisconsin Governor 2026 analysis →
Key Facts — Wisconsin
What This Means for Wisconsin Voters in 2026
Wisconsin voters in 2026 face a rare double opportunity: both the Senate seat and the governorship are competitive, and both could swing on the same structural dynamics. Democrats need strong turnout in Milwaukee and Madison, combined with modest suburban improvement in the WOW counties, to offset Republican margins in the rest of the state. Republicans need to hold their 2024 presidential coalition together without Trump at the top of the ballot — a challenge that has tripped up their candidates in off-year elections in Wisconsin before.
Key issues specific to Wisconsin: dairy and agriculture policy matters to the large farming communities in the central and western parts of the state; manufacturing employment in the Fox River Valley is politically sensitive; and access to abortion (following the state's 1849 law controversy) has been a major mobilizing issue for Democrats since 2022. Economic concerns and healthcare costs rank as top voter priorities statewide.
The national environment will matter enormously. If Trump’s approval ratings remain low heading into 2026, Democrats have a structural opening. If the economy stabilizes and Republican candidates run as moderates on social issues, they could consolidate the 2024 gains. In a state decided by fractions of a percent, every variable matters. See generic ballot polling and Trump approval tracking for current national trend data.
