And here is from Wikipedia:
Rubio grew up in a family that was Roman Catholic, though from age 8 to age 11, he and his family attended The Church of Jesus Christ of Latter-day Saints while living in Las Vegas, where his father worked as a bartender at Sam's Town Hotel and his mother a housekeeper at the Imperial Palace Hotel and Casino. He received his first communion as a Catholic in 1984, before moving back to Miami with his family a year later. He was confirmed and married in the Catholic Church.
Ted Cruz is Southern Baptist according to Wikipedia
Vote smart.org, just says Christian
Sorry but as I said in a later post once a Mormon always a Mormon as far as the church is concerned, same goes for Catholic so unless they kicked him out he still belongs to both as far as the churches are concerned. The Mormons are lax about removing the dead from membership roles.
Apparently Rubio frequents a Christian church in FL.
