The next race for a seat on the Wisconsin Supreme Court could cost $5 million with most of the money spent by outside interest groups, according to several news accounts on the court.  That would continue a pattern in Wisconsin where spending totaled about $12 million for two recent races for the top court with outside interest groups accounting for $8 million of that, Mike McCabe, executive director of the Wisconsin Democracy Campaign, told Milwaukee’s WISN.com News.  The Democracy Campaign this month reported that a majority of the Wisconsin State Legislature when it convenes next January will be on the record as having voted for or supported two campaign finance reform efforts.  Much work still must be done but prospects are positive for a measure that would bring public financing to Wisconsin Supreme Court races, said McCabe.  Last year, all seven justices of the state’s top court signed a letter written by Chief Justice Shirley Abrahamson that called for public financing of their races and sent it to the state legislature.   Abrahamson said her race this April could cost $5 million and such big spending threatens to “undermine what should be an impartial, fair judiciary,” according to the WisPolitics news service.  The problem is compounded because as few as 20 percent of eligible voters actually vote in a judicial race, she said. “Anyone with money can target that 20 percent and win an election,” said Abrahamson. “It’s your court not mine. It is very important to vote.”  And it’s important to have a Clean Elections-style financing system in place for judicial races. On Wisconsin.
