I'm a little late on this one, but this should come as no surprise:
(100%) 1: Pentecostal/Charismatic/Assemblies of God
(98%) 2: Anabaptist (Mennonite/Quaker etc.)
(98%) 3: Baptist (non-Calvinistic)/Plymouth Brethren/Fundamentalist
(89%) 4: Baptist (Reformed/Particular/Calvinistic)
(87%) 5: Lutheran
(65%) 6: Methodist/Wesleyan/Nazarene
(62%) 7: Congregational/United Church of Christ
(62%) 8: Seventh-Day Adventist
(60%) 9: Anglican/Episcopal/Church of England
(56%) 10: Presbyterian/Reformed
(50%) 11: Eastern Orthodox
(39%) 12: Roman Catholic
(35%) 13: Church of Christ/Campbellite
I was somewhat surprised by the 2. result, that seems quite off the radar. I also expected Roman Catholic to be a little higher on the list since I spent so much time in the Catholic church. Oh well.
