Why don't you get yourself a copy, read it, and decide for yourself?
Or are you just afraid that you might actually learn something that would conflict with your current viewpoint?
Well I've read articles by Graham where he expounded on his secession history and found them to be the same old Southron song-and-dance. He's got the usual claim that states 'seceded' from the Articles of Confederation to form a new country - the old 'seceded from the U.S. to form the U.S.' arguement that has never made any sense at all to me. He overblows secession sentiment in the New England states, as do all Lost Causers while at the same time conveniently forgetting that the consensus of opinion in the South was that such threats were treasonous. He disses Texas v White, par for the course. And on and on and on. The same old Southron position that the Constitution granted protections for some states and not for others which makes for the Orwellian "all states are equal but some are more equal than others" arguement that you Southron types love so well. So really, if the book is nothing but more of the same then I don't see the point in wasting my time. Sorry.
