I'll just give you my favorite line from the Hitchens article (which rips armchair psychologists who label Bush a "dry drunk," calls AA a "quasi-cult," and thinks he can figure out that Bush was never much of a drunk):
Winston Churchill was half in the bag for the whole of the Finest Hour, if not longer.
His conclusion is that Bush should drink now and then! Hitchens doesn't like teetotaling, because why should you trust someone who can't trust himself? And: "Nobody likes a quitter."
