The city of Waukesha has a new Democratic-backed mayor in traditionally red Waukesha County. Common Council president Alicia Halvensleben is the new mayor-elect, defeating Republican State Representative Scott Allen with 51% of the vote. Halvensleben won by approximately 450 votes to become the first Democratic-backed candidate elected in 12 years.

Why it matters

Waukesha County has long been considered a Republican stronghold in Wisconsin, so Halvensleben's victory represents a potential shift in local politics. The mayoral race was wide open after longtime Republican-turned-Independent mayor Shawn Reilly decided not to run for a fourth term.

The details

Halvensleben, the Common Council president, defeated Republican State Representative Scott Allen in a tight race. While Waukesha County and the city of Waukesha have voted overwhelmingly Republican in recent presidential elections, the margin of victory for Republicans has been shrinking. Some voters felt the city was trending more 'purple' in recent years.

  • Halvensleben was elected as the new Waukesha mayor on April 4, 2026.
  • Longtime mayor Shawn Reilly, a Republican-turned-Independent, decided not to run for a fourth term.
