Herman Cain's book

Why is the media claiming that the book is a distraction from a serious campaign? I think it was a smart move to write this book at a time when voters are trying to figure out who the candidates are. How many times has a newcomer arisen in an election and he gets a lot of press, but many people are asking, who is this? where is he from, what is his platform? what is his background, experience? Cain answered by setting out his autobiography in a nod to voters’ right to know who a presidential candidate is. And of course, he earns good money on it at the same time.
