Douglas boasted that the Democrats were a national party, whereas the "Black Republicans" were a sectional body whose creed could not be uttered south of Mason and Dixon's line. He was assiduous in fastening upon Lincoln the name of "Abolitionist," and "Black Republican," epithets so unpopular that those who held the faith often denied the title, and he only modified them by the offensive admission that Lincoln's doctrines were sometimes disingenuously weakened to suit certain audiences: "His principles in the north [of Illinois] are jet black; in the centre they are in color a decent mulatto; and in lower Egypt[83] they are almost white." Concerning sectionalism, Lincoln countered fairly enough on his opponent by asking: Was it, then, the case that it was slavery which was national, and freedom which was sectional? Or, "Is it the true test of the soundness of a doctrine that in some places people won't let you proclaim it?" But the remainder of Douglas's assault was by no means to be disposed of by quick retort. When Lincoln was pushed to formulate accurately his views concerning the proper status of the negro in the community, he had need of all his extraordinary care in statement. Herein lay problems that were vexing many honest citizens and clever men besides himself, and were breeding much disagreement among persons who all were anti-slavery in a general way, but could by no means reach a comfortable unison concerning troublesome particulars. The "all men free and equal" of the Constitution, and the talk about human brotherhood, gave the Democrats wide scope for harassing anti-slavery men with vexatious taunts and embarrassing cross-interrogatories on practical points. "I do not question," said Douglas, "Mr. Lincoln's conscientious belief that the negro was made his equal, and hence is his brother. But for my own part, I do not regard the negro as my equal, and positively deny that he is my brother, or any kin to me whatever." He said that "the signers of the Declaration had no reference to the negro,... or any other inferior and degraded race, when they spoke of the equality of men," but meant only "white men, of European birth and descent." This topic opens the whole subject of Lincoln's political affiliations and of his opinions concerning slavery and the negro, opinions which seem to have undergone no substantial change during the interval betwixt this campaign and his election to the presidency. Some selections from what he said may sufficiently explain his position.
