MADISON, Wis. (WTAQ) - About 10 percent of Wisconsin’s eligible voters will go to the polls for Tuesday’s state and local primaries.

The prediction comes from the state’s Government Accountability Board. But higher turnouts are expected in places with hot local contests.

In Green Bay, seven candidates are vying for two spots in April's general election, including incumbent Mayor Jim Schmitt. 4 candidates are in the primary race for Brown County Executive, to replace outgoing exec Tom Hinz.

Brown County Clerk Darlene Marcelle is predicting a 17 percent turnout at the polls for eligible voters and 21.7 percent of registered voters expected to cast a ballot.

In Madison, where there’s a mayoral primary, expects 25 percent to show up. But in many places, the only contest is a four-way primary for the State Supreme Court.

That’s turning out to be an interesting race on a couple of fronts. First, observers say incumbent David Prosser is the only conservative on the ballot. He’s facing public defender’s official Marla Stephens, assistant attorney general JoAnne Kloppenburg, and Madison attorney Joel Winnig.

Also, the Madison Capital Times says the primary will be a big test for the state’s new effort to keep special interests out of Supreme Court elections.

Tuesday’s contest is the first under a new law that gives public funding to Supreme Court candidates – and only Stephens has turned it down. As a result, she only had $38,000 in her campaign war chest at last word – while the other three each had $100,000 in public dollars to spend.

Stephens’ campaign manager says that if she wins the primary Tuesday, she’s banking on a big rush of special interest money to help her win the April election.

The top two vote-getters Tuesday will advance.
