Gary Wills in the New York Review of Books:
The right wing in America likes to think that the United States government was, at its inception, highly religious, specifically highly Christian, and even more specifically highly biblical. That was not true of that government or any later government—until 2000, when the fiction of the past became the reality of the present. George W. Bush was not only born-again, like Jimmy Carter. His religious conversion came late, and took place in the political setting of Billy Graham’s ministry to the powerful. He was converted during a stroll with Graham on his father’s Kennebunkport compound. It is true that Dwight Eisenhower was guided to baptism by Graham. But Eisenhower was a famous and formed man, the principal military figure of World War II, the leader of NATO, the president of Columbia University—his change in religious orientation was just an addition to many prior achievements. Bush’s conversion at a comparatively young stage in his life was a wrenching away from mainly wasted years. He joined a Bible study culture in Texas that was unlike anything Eisenhower bought into.
Bush was a saved alcoholic—and here, too, he had no predecessor in the White House. Ulysses Grant conquered the bottle, but not with the help of Jesus.
