Keep preaching your 'it was all about slavery' while you can. We are finally seeing the fruits of lincoln's EMPIRE. Keep up your praise of lincoln and 50 years from now you'll know who to thank for the situation this country will be in.
In 1863 General Cleburne of the Confederate Army of the Tennessee circulated a memo arguing that since the South was losing a war of demographic attrition, it's only hope was to enlist blacks. And the only hope of enlisting blacks lay in emancipation. For that memo, he was passed over for command of the Army of the Tennessee. Everyone soldier in that army knew that Cleburne should have been commanding the army, not Bragg or Hood which caused severe morale problems.
If there had been any Southern nationalism, blacks would have been emancipated and enlisted because the 10% of the Union Army that was black was the North's margin of victory, as Lincoln admitted. A nation does what it has to in order to survive. But minus slavery there was no real point in the Confederacy so this was never done.
And conservatives wonder why they never make any headway with black voters.
