Rubio is as much of a digbat as Willard Romney. This article says Rubio was baptised in the Morman faith. He went from being a Catholic to being a Morman, now back to Catholic again. He’s not much of Catholic and commits a sin against his Church by not going to Mass, by now attending a Baptist church. This is a weird man folks.
He sounds to me like a big time opportunist who plays to whatever crowd he’s trying to get a vote from.

His family was Catholic and went to lds when he was a kid. As an young adult he returned to Catholicism, now attends a Baptist Church, which he and his family have been attending for years.. I am not sure why that is an issue.
