Well, this could affect Mitt Romney's vice presidential pick:

In the compelling personal narrative that has helped propel Florida Senator Marco Rubio to national political stardom, one chapter has gone completely untold: Rubio spent his childhood as a faithful Mormon.

Rubio was baptized into the Church of Jesus Christ of Latter-day Saints with his family at around the age of eight, and remained active in the faith for a number of years during his early youth, family members told BuzzFeed.

Rubio spokesman Alex Conant confirmed the story to BuzzFeed, and said Rubio returned to the Catholic church a few years later with his family, receiving his first communion on Christmas day in 1984 at the age of 13.

There's much more, including the Rubio family's love of the Osmonds, in the Buzzfeed story. I just can't see super-cautious Romney going for a vice presidential candidate who has even a relatively harmless tie to the Mormon church, even though Rubio is the party's favorite son right now.
