"I confess to feeling continued ambivalence about political life, aware of its shortcomings and disappointments, but drawn back to it again and again because of its infinite promise. Justice can triumph, wrongs can be righted, and pain can be alleviated, if the right fix is found. The optimistic illusion that one can change the world is difficult to resist, especially when from time to time that illusion is sustained by even a hint of reality. Change does happen in the political process."
