Rick Santorum and Louisiana Governor Bobby Jindal will board the “No Wiggins Bus Tour” when it departs next week.

The 17-city tour is 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.

The bus tour was announced earlier this month by The FAMiLY LEADER President Bob Vander Plaats. Co-sponsoring the tour are the National Organization for Marriage (NOM) and CatholicVote.org.

Santorum will join the tour for stops in Des Moines, Pella and Ottumwa on Monday. Jindal will board the bus on Wednesday.

“It is obviously clear the people's Constitution gives the judicial branch the least power, and yet these appointed judges continuously legislate from the bench whether it is gay marriage in Iowa, collective bargaining in Wisconsin, or resulting in the death of millions of lives caused by the opinion of Roe v. Wade,” Santorum said in a statement.

Jindal added: “From the top of the ticket on down, our freedoms and values are at stake. It's critical we do everything we can to encourage conservatives to go to the polls and vote to uphold our values, freedoms and constitutional rights.”
