” Bob Vander Plaats, president of The Family Leader (right) speaks before a bus tour to urge Iowans to vote state Supreme Court Justice David Wiggins off the bench, in Des Moines, Iowa, on Monday.

A battle is under way in Iowa over whether a state Supreme Court justice can keep his job.

Critics have launched an all-out campaign to throw him off the bench because of his ruling three years ago clearing the way for same-sex marriage. The judge’s supporters are fighting back, but they may need to get over their reluctance to mix politics and the judiciary.

Christian conservatives are still energized by their victory in 2010, when they voted down three justices for their same-sex marriage ruling. Judges in Iowa are appointed, not elected, but they face periodic retention votes to keep their jobs.

This year, Justice David Wiggins is on the ballot. And the conservatives are taking their “No Wiggins” campaign on a bus tour this week. Former GOP presidential candidate Rick Santorum spoke at the start of the tour on Monday. Boarding the bus near the state capital, evangelical leader Bob Vander Plaats rallied for a repeat of the 2010 vote.”
