'But I do know this'

Andrew Sullivan, a Brit, got his Green Card today. He writes, in part: "And I do not know right now what to do or say. But I do know this. America remains the great dream, the great promise. For all its dysfunction, it remains an ideal, a place where the restlessness of the human mind and soul comes to rest in a place it constantly reinvents and forever re-imagines. I know this in my bones, perhaps more than many who take this amazing mess of a country for granted." Well said.
