I've got "The Real Lincoln" although it has been at least five years since I've read it. The gist of it is that Lincoln was a lawyer who got rich working for railroads in his native Illinois. As such, he was a Whig guy who supported a mercantilist system and that he was bought and paid for by the railroads. He only fought the Civil War in order to keep the revenues coming.
As for the "Nullification crisis" none other than Jefferson Davis in his farewell address to the Senate in 1861 did a masterful job of differentiating between nullification and secession. Of course, most people don't know that because it isn't PC to study stuff said by Jefferson Davis.
