"If Jefferson and the Founders knew that all men are created equal, why not outlaw slavery from the outset? The simple answer is that had they done so, there would never have been a union. Historian Eugene Genovese states the obvious, "If the Constitution had not recognized slavery, the Southern states would never have entered the union." So the choice facing the Founders in Philadelphia was not whether to have slavery or not. Rather, it was whether to have a union that temporarily tolerated slavery, or to have no union at all."
