Why Does This Book Exist?

I'm trying to figure out why this book exists.

I should say this: I'm only 90 pages into it, so a little less than half. But still I wonder: Who is this book for?

Old farts like me recognize the name of Tom Brokaw. He was a mainstay of the news in the 80s and longer, when I was growing up and going to school. And as Brokaw was a rookie television reporter assigned to Washington during the Nixon impeachment years, it's natural that Brokaw would write a book about it.

But why does this book exist?

There's been little of the story sofar, and what is there is stuff you could probably find in a Wikipedia article on the Watergate scandal. Outside of that, there's a lot of name-dropping. Lots of name-dropping. So this is more of a memoir, I suppose, with the "fall of Richard Nixon," -- one of the book's two subtitles -- playing in the background.

I'll give it a fair shake and finish it, of course. But it's thusfar the least informative Nixon book I've ever read.
