Aftermath

With this election Democrats held a trifecta in the Wisconsin government for the first time since 1982, when Tony Earl was elected governor of Wisconsin.
As of 2025, this is the last time Democrats gained a trifecta in Wisconsin, as despite winning the popular vote several times in following elections, a Republican instituted gerrymander in 2011, in addition to low voter turnout, prevented Democrats from gaining a majority of seats.
