Two years ago, in what should have been a quiet judicial retention election, Iowa voters threw out three State Supreme Court justices for taking seriously their duty to protect fundamental rights. The three had provoked right-wing wrath for joining a unanimous 2009 ruling overturning the state’s prohibition on same-sex marriage. Conservative forces succeeded in ousting them by tapping antigay sentiment and attacking “activist” judges. Those same forces — aided openly this time by the state’s Republican Party — are now calling for the removal of David Wiggins, another capable judge who joined in the marriage decision.
