Query: A must read for all especially in Detroit.

I read this book after reading David Barton's American history in Black and White. I've always been fascinated by the majority of African Americans who overwhelmingly support Democrats in general, and wanted to get a a little bit more information on how this happened and how so. This book by Mr Perryman greatly depicts the reason why and I'm really surprised on how it all happened. A must not just for african americans but for everyone.
