MADISON, Wis. (AP) -- A candidate for Wisconsin Supreme Court who has already declared he is a Democrat is now calling on other candidates in the race, including a sitting justice, to state their political ideology.

Milwaukee lemon law attorney Vince Megna issued the call on Wednesday, saying it is the only way for a fair and truthful election.

Races for the Supreme Court are officially nonpartisan, with candidates not affiliated on the ballot with any particular political party. However, in recent years conservatives and Republicans have tended to back one candidate while Democrats and liberals have lined up with another.

Megna is running against incumbent Justice Patience Roggensack, who has hired a former executive director of the state Republican Party to run her campaign. Marquette University law professor Ed Fallone is also running.
