Rick Santorum on the Colbert Report

The former U.S.senator hasn't ruled out another bid to win GOP presidential nomination.

Rick Santorum went on the Colbert Report to promote his film, The Christmas Candle--and maybe to signal that he just might throw his hat in the ring for the 2016 GOP presidential primaries.

The brief exchange also covered same-sex marriage. Colbert asked him if it was too late to stop the "marriage equality" juggernaut, and Santorum reframed the issue, arguing that it was time to re-claim the meaning of marriage. Check it out here.
