Wisconsin has focused on the Green Bay Packers and Gov. Scott Walker for the last month, but another fight with perhaps just as much impact on the state is about to take center stage -- the state Supreme Court primary.

Justice David Prosser faces three challengers. Voters on Tuesday will choose two survivors who will face off in April's general election. The winner gets a 10-year term on the court.

The primary has played out in the background as the Packers charged to a Super Bowl title and Walker proposed doing away with state workers' unions. But the general election could ultimately tilt the ideological balance of the court for years to come.

State election officials expect about 10 percent of the state's voters will venture to the polls Tuesday.
