Todd Madson takes note of the signs in his neighbors' yards when he goes campaigning door-to-door in Orono.
The father of two and first-time school board candidate gravitates toward homes that display support for a conservative slate campaigning on policy proposals diametrically opposed to his.
Those residents typically want to talk about issues that have nabbed headlines over the last two years, such as critical race theory and inclusivity for LGBTQ people.
"The questions are out there," said Madson, who supports diversity and equity initiatives. "And I think it's because it's a national conversation that's happening."
School board races have often been hyperlocal or low-energy affairs. But over the last few years, those contests have become ever more polarized, drawing on national culture war debates and energized by disputes over how schools handled pandemic precautions, from masks to distance learning.
That's a shift from the past when conservative school board candidates were driven to run by a desire to rein in district budgets, said Larry Jacobs, director of the Center for the Study of Politics and Governance at the University of Minnesota.
"The national battle over social issues is coming home to roost, here in Minnesota and in conservative areas where you might not expect that," Jacobs said. "There's a new type of conservatism. It's not just budget issues. It's also social issues."
Last year, several conservative candidates campaigned together, pooling their resources and running as slates in an effort to gain majorities on school boards in Twin Cities suburban districts. Voters largely rejected those candidates.
