In her opinion essay in The National Law Journal about special-interest spending in judicial elections, former Iowa Chief Justice Marsha Ternus urged “keeping politics out of the courtroom.” ( “Politics on the Bench—A Judge’s View of Partisanship at Play,” Jan. 20.) Her concern is understandable: She and two colleagues were ousted in a 2010 retention election after the court in 2009 ruled unanimously that an Iowa statute denying civil marriage to same-sex couples violated equal protection under the Iowa Constitution. But there’s more politics here than meets the eye. In fact, it’s the politics Ternus didn’t mention that seems to have colored her idealized view of judging, shielding her from a deeper account of why our courts have become so politicized.

Far from the angels being all on one side, it turns out that Iowa’s “nonpartisan” judicial screening commission and gubernatorial appointment process is deeply political. As a July 2010 report by The Iowa Republican documents, not only were all seven members of the Iowa Supreme Court, save Ternus, nominated by Democratic governors, from lists presented by the commission, but all were or had been Democrats or had made significant contributions to the party or its candidates. All seven, in short, came from one party.
