Rick Santorum, Bobby Jindal to join social conservative bus tour in Iowa

Former Pennsylvania Republican Sen. Rick Santorum heads to Iowa next week to join a bus tour led by the social conservative group the Family Leader, furthering speculation that he's looking ahead to another presidential run in 2016 if President Barack Obama defeats challenger Mitt Romney in November.

The bus tour, which takes place Sept. 24 to Sept. 27, will take Santorum to Des Moines, Pella and Ottumwa on Monday the 24th. It's intended to protest retaining Iowa Supreme Court Justice David Wiggins, who joined the 2009 ruling that made same-sex marriage legal in Iowa.

The Family Leader endorsed Santorum for president in 2011.

Louisiana Republican Gov. Bobby Jindal will also join the tour and is scheduled to travel to Mason City, Marshalltown, Fort Dodge and Carroll on Wednesday the 26th.
