MADISON, Wis. (WTAQ) - Almost three of every 10 Wisconsin voters are expected to cast ballots in the fall primaries in 12 days – and that would be a record turnout for September.

The Government Accountability Board said today that 28 percent of eligible voters are likely to cast ballots on September 14th. Board director Kevin Kennedy credits the highly-contested statewide races for governor and U.S. Senate, along with more localized congressional and state legislative primaries.

The highest recorded September turnout in the last 50 years happened in 1964, when 27.9 percent of Wisconsin voters showed up at the polls. This year, there are 6 primaries for statewide offices, and primaries in 7 of the 8 U.S. House districts.

There’s no incumbent running for governor for the first time since 1986, after Jim Doyle decided to call it quits. And the voters will decide whether Republicans Scott Walker or Mark Neumann will face Democrat Tom Barrett in November.
