Because it was purported that these books would show a dffernt side to the story; as yet, they have not.
The clear implcation is that they will not, and cannot refute the sovereign nature of United States and all the rest of the readily avialble record that N-S, X, myself and others have put up.

Considering the source of the above statement, I tend to be skeptical of the assertion. Most likely the issue fails to involve whether or not a different side was offered in those books, but rather involves the openness of one particular individual to acknowledge and consider that different side when it is presented, no matter what its historical merits may be. As evidenced by that individual's behavior here, history matters not when it contradicts his annointing of Lincoln as the secular diety of anti-slavery.
