Autobiography of a guy who did political opposition research back when that meant travelling to county seats and looking at old voting records on microfilm or somesuch. He mostly worked for right-wing candidates digging up "dirt" on left-wing candidates where "dirt" all too often meant: voting to increase taxes or increase spending. But there are also stories of bringing actual corruption to light, both on the left and on the right. So I guess read this book if you ever find yourself feeling insufficiently cynical about politics or something?
