MADISON, Wis. (AP) – Voters will narrow the field of seven candidates seeking to become Wisconsin’s top education official. The top two vote-getters on Tuesday in the officially nonpartisan race to be secretary of the Department of Public Instruction will advance to the April 6th general election. Polls were open statewide Tuesday from 7 a.m. to 8 p.m. State election officials expected turnout to be low for the race, which is the only statewide contest on the ballot. There were also two Republican primaries for open legislative seats.
