What denomination of Christianity does Barack Obama claim to belong?

First, there is considerable evidence his belief in Christianity is more than just a "claim." Based on his public statements as well as his writings, he is a Protestant, and seems to be a moderate; this has caused certain conservative Christians to accuse him of not being Christian at all. But while he does not follow a fundamentalist version of the Christian faith, Christianity does seem important to his family life. He has attended church services from several Christian denominations over the past several decades, including the Methodists and the United Church of Christ. He and his wife Michelle have also said they are raising their children as Christians; but they have not spoken much about which denomination they prefer.
