Republican candidate Rick Gundrum has won the GOP primary for the 58th State Assembly District special election Tuesday.

The contest is to replace state Rep. Robert Gannon, who died in October. Gundrum is chairman of the Washington County Board of Supervisors and is a village trustee in Slinger.

During an Tuesday night interview at his victory party in Slinger, Gundrum thanked his supporters. He also said his fiscal conservatism and "100 percent pro-life" policies helped him carry the race.

Gundrum said he opposes all abortions, including when the woman is raped or a victim of incest, or when her life is in danger if the baby is delivered.

The second-place finisher was Tiffany Koehler, a former aide to Gannon who ran for the seat in 2014. Business owner Steve Stanek finished third and Spencer Zimmerman, a chauffeur and flight line technician, finished last.

It's a heavily Republican district northwest of Milwaukee, but Democrats have fielded a candidate. Dennis Degenhardt, a former credit union executive, will face Gundrum in the Tuesday, Jan. 16 general election.
