The Wisconsin Governor race 2026 has entered the general-election stage, with Democrat David Crowley and Republican Tom Tiffany competing to become Wisconsin’s next governor. The contest is scheduled for November 3, and recent polling shows a close race with a meaningful share of voters still undecided.
Crowley, the Milwaukee County executive, won the Democratic nomination in a remarkably close primary on August 11. Tiffany, a Republican U.S. representative from Wisconsin, won his party’s nomination by a much wider margin.
The latest Marquette Law School Poll gives Crowley a 49% to 44% advantage among likely voters, with 7% undecided. Among all registered voters, the candidates were tied at 44% each, while 12% had not decided.
The numbers show that the November election remains competitive. Neither candidate has established a commanding statewide advantage.
David Crowley wins the Democratic nomination
Crowley emerged from one of Wisconsin’s most closely watched Democratic primaries.
He defeated state Rep. Francesca Hong by a narrow margin after a competitive campaign. Hong had developed strong support among progressive voters and made issues such as data-center development an important part of her campaign.
Crowley’s victory placed him in the general election against Tiffany.
The Milwaukee County executive brings statewide political experience and a long record in Wisconsin government. He previously served in the Wisconsin State Assembly before becoming Milwaukee County executive.
Crowley won reelection as county executive in 2024.
His campaign has emphasized affordability, housing, health care, education, wages and economic opportunity. He has also highlighted his support from organized labor and his record in Milwaukee County.
A victory would make Crowley Wisconsin’s first Black governor.
That historic possibility has become another important element of his campaign as he works to build support beyond Milwaukee County.
Tom Tiffany wins the Republican nomination
Tiffany entered the general election after dominating the Republican primary.
He won approximately 95% of the Republican vote, defeating Andy Manske by a huge margin.
The result allowed Tiffany to quickly shift his attention toward the November contest.
Tiffany has represented Wisconsin in Congress since winning a special election in 2020. Before moving to Washington, he served in the Wisconsin Legislature.
He also received the endorsement of President Donald Trump during the campaign.
Tiffany’s campaign has focused on lower taxes, government spending, energy costs, public safety and opposition to policies he considers too liberal.
His congressional record and connection to the national Republican Party are likely to remain central elements of the campaign.
Latest polling shows a close contest
The latest major statewide poll provides a useful snapshot of the race.
Among likely voters, Marquette Law School found:
| Candidate | Support |
|---|---|
| David Crowley | 49% |
| Tom Tiffany | 44% |
| Undecided | 7% |
Among all registered voters, the result was different:
| Candidate | Support |
|---|---|
| David Crowley | 44% |
| Tom Tiffany | 44% |
| Undecided | 12% |
The difference between the two groups is important.
Crowley performs better in the likely-voter sample partly because Democratic voters reported a slightly stronger intention to participate in November.
Independent voters also give Crowley an advantage in the survey. Among likely independent voters, Crowley received 55% support compared with 16% for Tiffany, while 30% remained undecided.
Among registered independent voters, Crowley led 35% to 18%, but 47% had not chosen a candidate.
That leaves a large group of independent voters who could still influence the outcome.
Affordability remains a major concern
Economic issues are at the center of the governor’s contest.
The latest Marquette polling found inflation and the cost of living among the most important concerns for Wisconsin voters.
Both campaigns have responded by emphasizing economic issues, although they offer different approaches.
Crowley has focused heavily on the expenses facing families. His campaign has discussed housing, health care, child care, wages and property taxes.
Tiffany has emphasized reducing taxes and government spending while criticizing policies that he says increase costs for Wisconsin residents.
The economic debate gives both candidates an opportunity to appeal to voters who may not be strongly aligned with either party.
Data centers become a major campaign issue
Data-center development has quickly become one of the defining issues in the governor’s race.
The issue gained significant attention during the Democratic primary and continued into the general election.
Both Crowley and Tiffany support stronger rules for data centers, but they have attacked each other over their approaches.
Tiffany has argued that Wisconsin should prevent large technology projects from placing additional costs on residents and communities.
His campaign has called for an end to taxpayer subsidies for data centers, greater local control, protection of farmland and measures requiring projects to pay costs associated with infrastructure and electricity.
Crowley also supports giving local communities a role in deciding whether data centers should be built.
His campaign has called for developers to cover infrastructure and grid-upgrade costs. He also supports renewable energy requirements, transparency and protections for water and other natural resources.
The issue has political significance because voters have expressed substantial concern about the potential effects of large data centers on electricity, water, farmland and local communities.
The candidates therefore face pressure to explain not only whether data centers should be allowed but also what rules should govern future development.
Prison policy creates another difference
Public safety and corrections policy have also emerged as issues separating Crowley and Tiffany.
Tiffany has said Wisconsin needs additional prison capacity as the state’s incarcerated population reaches a record level.
Crowley has taken a different position, favoring reduced prison time for some nonviolent offenders rather than relying primarily on additional prison construction.
The disagreement provides voters with a clear policy contrast.
Tiffany’s approach emphasizes additional capacity and a tougher response to incarceration needs.
Crowley’s approach places greater emphasis on reducing incarceration for certain nonviolent offenses.
The issue could become more prominent as the campaigns continue discussing public safety and state spending.
Tiffany’s emergency plane landing
A major development in the race occurred on September 13 when Tiffany survived an emergency plane landing on Lake Wausau.
Tiffany was returning from a political event in La Crosse County when the aircraft lost power while approaching Wausau Downtown Airport.
The pilot successfully brought the single-engine aircraft down on the lake.
The plane began sinking after landing. Tiffany and the pilot escaped and swam toward shallow water before emergency responders reached them.
Both men were taken to Aspirus Wausau Hospital for treatment.
Tiffany suffered a cut above his eye that required stitches. The pilot also sustained minor injuries.
Both were released from the hospital.
The Federal Aviation Administration is investigating the incident.
Tiffany has said the event will not end his campaign. He also publicly thanked the pilot and emergency responders for their actions.
Crowley expressed relief that neither Tiffany nor the pilot suffered serious injuries and praised the pilot’s response.
The incident has added an unexpected development to the campaign less than two months before Election Day.
Crowley faces the challenge of uniting Democrats
Crowley’s primary victory solved one major problem but created another political task.
He must now bring together Democratic voters who supported Hong.
Hong’s campaign attracted progressive voters who wanted stronger restrictions on data centers and a more left-leaning approach to state government.
Crowley’s political positioning differs from Hong’s in several areas.
The Democratic nominee therefore needs to maintain support from the party’s progressive voters while also attracting independents and moderate voters.
The latest Marquette poll provides some encouraging signs for Crowley.
Ninety-eight percent of likely Democratic voters surveyed said they supported Crowley. However, the large number of undecided independent voters means his general-election coalition still has room to grow.
Tiffany seeks to broaden his support
Tiffany enters the general election with strong Republican support.
The Marquette poll found that 91% of likely Republican voters supported him, while only 6% remained undecided.
His challenge is to expand beyond that base.
Independent voters currently favor Crowley in the polling, making this group particularly important for Tiffany.
The Republican campaign has emphasized taxes, energy, government spending, public safety and data centers.
Tiffany also benefits from a strong connection to the Republican Party’s national leadership.
His endorsement from Trump could help energize Republican voters, although the campaign still needs to appeal to Wisconsin voters who do not consistently vote Republican.
Why independent voters matter
Independent voters could play an important role in deciding the governor’s race.
The latest polling shows a much higher level of uncertainty among independents than among Democrats or Republicans.
That creates an opportunity for both candidates.
Crowley has an early advantage, but 30% of likely independent voters in the Marquette survey remained undecided.
Among all registered independent voters, the undecided share reached 47%.
Those numbers demonstrate why current polling does not provide a final outcome.
The candidates still have substantial time to introduce themselves, define their policy positions and persuade voters who have not settled on a choice.
Campaign messages take shape
Crowley has sought to make the election about household costs and practical government priorities.
His campaign emphasizes affordability and economic opportunity while defending his record in Milwaukee County.
Tiffany has worked to make the campaign about taxes, spending, public safety and regulation.
His attacks on Crowley’s position on data centers have also become an important part of the Republican campaign’s messaging.
The two candidates are therefore attempting to move the election toward issues that favor their respective coalitions.
That competition over the central campaign narrative will become more important as November approaches.
What voters will watch before November
Several issues are likely to remain central during the final campaign period.
Affordability: Inflation, housing, health care, utilities and taxes remain major concerns for Wisconsin voters.
Data centers: The candidates have different approaches to regulation, local control, energy use and development.
Public safety: Prison capacity and criminal-justice policy provide another clear difference between the nominees.
Independent voters: A large number remain undecided, giving both campaigns an opportunity to gain support.
Turnout: The difference between registered-voter and likely-voter polling highlights the importance of participation.
Candidate favorability: Both candidates have room to improve their standing with voters who have not yet formed strong opinions.
Election Day is November 3
Wisconsin voters will choose their next governor on November 3, 2026.
The primary contests have already established the nominees, leaving voters with a direct choice between Crowley and Tiffany.
Crowley enters the general election with a modest polling advantage among likely voters.
Tiffany enters with strong Republican support and a large primary victory.
Neither position guarantees success.
Wisconsin’s political environment remains competitive, and the latest polling shows that independent voters could play a major role.
The candidates also face different coalition-building challenges.
Crowley needs to maintain Democratic unity while expanding his support among independents and moderates.
Tiffany needs to maximize Republican turnout while making gains among voters outside the Republican base.
The coming weeks will determine which campaign succeeds at those tasks.
The Wisconsin governor contest remains wide open
The latest numbers show why the governor’s race continues to command attention.
Crowley’s 49%-44% lead among likely voters gives the Democrat an early advantage, but the 44%-44% result among registered voters shows how close the broader electorate remains.
Seven percent of likely voters and 12% of registered voters were undecided in the Marquette survey.
That leaves both candidates with an opportunity to shape the final stage of the campaign.
The contest now centers on affordability, data centers, public safety, taxes, economic policy and the broader direction of Wisconsin state government.
With Crowley and Tiffany officially facing each other in November, every major campaign development can affect how voters view the two nominees.
