Jill Underly, Wisconsin’s state superintendent of public instruction, is seeking a second term in an office that helps oversee the state’s public schools. Though the race is officially nonpartisan, Ms. Underly is running with support from the Wisconsin Democratic Party and teachers’ unions, while her challenger, Brittany Kinser, is supported by the Republican Party.
