For many years God was a registered independent. He mainly spoke to the government through Reverend Billy Graham, who has met with and advised every president from Harry Truman through George W. Bush. Graham has seldom been publicly political, and according to Wikipedia:
Politically, Graham has been a registered member of the Democratic Party and leaned Republican during the presidency of his friend Richard Nixon. He has not completely allied himself with the religious right, saying that Jesus did not have a political party. He does not openly endorse political candidates, but he has given his support to some over the years.
He refused to join Jerry Falwell’s Moral Majority in 1979, saying: “I’m for morality, but morality goes beyond sex to human freedom and social justice. We as clergy know so very little to speak with authority on the Panama Canal or superiority of armaments. Evangelists cannot be closely identified with any particular party or person. We have to stand in the middle in order to preach to all people, right and left.”
