Counties will canvass the vote starting next week to determine the official margin of victory. The last time there was a recount in a Wisconsin Supreme Court race was in 2011.

The last statewide election was for the presidential race in 2016. That cost local election clerks $2 million, which is more than the $1.7 million Neubauer raised during the entire Supreme Court campaign. However, those costs included overtime for clerks who had to count nearly 2.9 million votes, more than double the 1.2 million cast in this year's Supreme Court race.

Wisconsin's Supreme Court race, the only statewide election of the year, was viewed as a barometer of voter moods heading into the 2020 presidential year. Turnout was strong at nearly 27%, beating the 2018 Supreme Court turnout of 22%, and the tight outcome provides more evidence of how evenly divided Wisconsin is.

President Donald Trump carried the state by less than a percentage point, and Walker lost by just over 1 point.

Hagedorn's victory in battleground Wisconsin sends a "message to all of America that we're ready to keep Wisconsin red as we turn our attention to mobilizing for 2020 and re-electing President Trump," said Mark Jefferson, executive director of the Wisconsin Republican Party.
