Oak Creek Mayor Dan Bukiewicz defeated Republican Dylan Pfaffenbach to win Wisconsin's 21st Assembly District, flipping a Milwaukee-area seat that Republicans had controlled since 2013. The district covers parts of Milwaukee's southern end around Milwaukee Mitchell International Airport along with the city of Oak Creek.
Reported vote totals from the night differed depending on the outlet. According to Urban Milwaukee, Bukiewicz won 59% of the vote with all in-person votes counted, while The Daily Cardinal first called the race for Bukiewicz and then reported him leading Pfaffenbach 60% to 40% in its live election-night coverage. Either way, the result ends Republican Jessie Rodriguez's long hold on the seat, which she won in 2013 and kept until she chose not to seek reelection this cycle after nearly 13 years in office, per the Urban Milwaukee report and the Milwaukee Journal Sentinel.
An Open Seat, An Endorsement, And A 21-Year-Old Challenger
Rodriguez didn't just step aside quietly — she endorsed Pfaffenbach to succeed her, the Journal Sentinel reported. Pfaffenbach, who was 21 years old during the race per Urban Milwaukee's reporting, ran with backing from Rodriguez, former Milwaukee alderman Bob Donovan, state Sen. Julian Bradley, and Patti Logsdon, along with the Milwaukee Police Association and the Milwaukee Deputy Sheriffs' Association. His campaign presented him as a moderate, while Democrats countered by casting him as an extreme right-wing candidate, according to Urban Milwaukee's reporting.
That characterization drew on Pfaffenbach's online history: he deleted tweets attacking abortion rights supporters and had called a congressional inquiry into the January 6 insurrection a “criminal board,” per the same Urban Milwaukee report. Bukiewicz, meanwhile, arrived with his own institutional résumé. He has served as Oak Creek's mayor since 2017 and is president of the Milwaukee Building and Construction Trades Council, a post he's held since 2014 representing more than 15,000 union tradespeople, according to WUWM. He secured the Democratic nomination by defeating David Liners in the August 11 primary, the station reported.
Money Poured Into A Seat Both Parties Needed
District 21 was no afterthought for either side. WUWM described it as one of the Republican-held swing seats under Wisconsin's newer legislative maps, and the Journal Sentinel noted that Kamala Harris carried the district by 4.1 percentage points in the 2024 presidential election. Wisconsin Watch's 2024 voter guide had already flagged the suburban Milwaukee seat, which then encompassed portions of South Milwaukee and Oak Creek, as a toss-up with no contested primary on either side that year.
The financial stakes were steep heading into Tuesday. The Assembly Democratic Campaign Committee, controlled by Greta Neubauer, spent $1.2 million seeking to win the district, while the Republican Assembly Campaign Committee provided more than $314,000 to Pfaffenbach's campaign, per Urban Milwaukee's reporting. Bukiewicz also drew union support, with contributions from the International Union of Operating Engineers Local 420 and Plumbers Union Local 75, the outlet reported.
A Statewide Cash Gap With Local Consequences
The spending in District 21 reflected a much larger imbalance statewide. From July 1 through October 19, the Assembly Democratic Campaign Committee raised around $5.1 million compared with roughly $281,000 for the Republican Assembly Campaign Committee, Urban Milwaukee reported in a separate article on legislative fundraising. Despite that gap, Republican committees actually outspent Democrats in the campaign's closing weeks, which Urban Milwaukee attributed to the GOP groups' larger cash reserves built up over time.
The broader context explains why one seat mattered so much. Republicans held a 54-45 majority in the Assembly heading into the election, meaning Democrats needed to flip at least five seats statewide to win control, according to Wisconsin Watch. The Journal Sentinel noted this marked the second election held under legislative maps enacted in 2024, maps that replaced a 2011 partisan gerrymander Urban Milwaukee's reporting described as having entrenched Republican control of the Legislature for more than a decade. Redistricting made District 21 competitive in a way it hadn't been under the old lines, per that same reporting.
Money flowed into other contested Assembly races as well. In a separate 2026 race, the Republican Assembly Campaign Committee had given candidate Bob Donovan about $1.3 million, according to Wisconsin Public Radio, underscoring how aggressively both parties' campaign arms worked to defend or expand their footholds this cycle.
