Rick Santorum, Bobby Jindal and Brian Brown were among the conservatives on board the “No Wiggins Bus Tour” last week.

The 17-city tour was part of the campaign to oust Iowa Supreme Court Justice David Wiggins, one of the seven judges whose unanimous 2009 ruling brought gay marriage to the Midwest.

Wiggins faces a nonpartisan retention vote on November's ballot. In 2010, social conservatives, angry over the gay marriage decision, axed three judges from the bench. The remaining three justices are up for retention votes in 2016.

Santorum, who lost the GOP presidential nominating contest to Mitt Romney, joined the tour at stops in Des Moines, Pella and Ottumwa.

“Ten years from now, your children or your grandchildren will look at you and say, 'Well what did you do?' What did you do at this moment that we all knew was a consequential moment in the history of this country. What did you do?” Santorum asked.

Brian Brown, the president of the National Organization for Marriage (NOM), the nation's most vociferous opponent of gay marriage, called on supporters to “change the course of history.”

“Take a bold stand,” Brown said. “Do not allow activist judges to rewrite your constitution. Hold them accountable. And the world will be watching.”

Louisiana Governor Jindal said Wiggins “does not have the right to usurp the powers of the office of governor and the Legislature and create that law from the bench.”

Iowa Rep. Steve King and The FAMiLY LEADER President Bob Vander Plaats also spoke at the rallies.
