Inside the supper club, I met state Rep. Donna Rozar, a Republican who told me she’d been “disappointed, obviously” with the election. She called the political climate “challenging,” which is the assessment of Republicans pretty much everywhere in Wisconsin.

“We got our butts kicked,” Rohn Bishop, Bachleitner’s predecessor as chair of the Fond du Lac County GOP and, now, mayor of the small city of Waupun, told me. “What the Republican base demands and what independent voters will accept are growing further apart.”

Bishop and I were eating lunch in a bar. The only way forward for the GOP in Wisconsin, joked a man drinking Jack and Coke beside us, might be to “kill the millennials.”

It wasn’t long ago that no Republican in Wisconsin was talking like that. Donald Trump in 2016 carried the state for the Republican Party in a presidential race for the first time since 1984. And even after Biden won it back for the Democrats in 2020, there was — and still is — a credible case to be made that of all the swing states, Wisconsin might be the likeliest for Republicans to flip in 2024.

For one thing, its demographics, unlike the rapidly diversifying states of Georgia, Arizona or Nevada, still look good for the GOP. In the 2020 election, 86 percent of voters were white, while people without college degrees — one of the Republican Party’s most reliable constituencies — made up two-thirds of the electorate. The state’s incumbent Republican senator, Ron Johnson, who entered his reelection campaign last year as one of the most vulnerable incumbents in the country, won one of the year’s most expensive Senate races.

And even in the April elections, two conservative-backed ballot measures passed — one making it harder for people to get out of jail on bail, the other an advisory-only measure in which Wisconsinites said able-bodied, childless adults should be required to look for work in order to receive welfare benefits.
