The state Government Accountability Board is predicting that 3.2 million votes will be cast. That is 74 percent of the 4.3 million people in the state who are of voting age.
The previous highest turnout percentage was 73 percent in 1960. In 2004, 72.9 percent of the voting age population voted.
The largest number of people who ever voted was in 2004 when just over 3 million cast their ballots in the state. That year Democrat John Kerry barely edged President Bush in Wisconsin.
This year interest in the presidential race between Democrat Barack Obama and Republican John McCain has been intense, with record-high absentee voting occurring in the days leading up to the election next week.
