[T]he very people who write so disparagingly about it either do not understand it, or I suspect even more, understand it all too well and do not like… - Allen C. Guelzo

What the Democratic Party has most liked to say about itself—that it is the party of the working man, the voice of the oppressed, the tribune of the people—loses some of its strut in the light of a rather long list of inconvenient facts, chiefly having to do with slavery and race. Such facts as these: that the Democrats were the party that championed chattel bondage, backed an expansionist war to expand slavery's realm, and corrupted the Supreme Court in order to open the western territories to the cancer. The party's Southern wing then led the nation into civil war in defense of slavery while its Northern wing did its best to stymie the administration of Abraham Lincoln, widely regarded by the Democrats as an accidental, even illegitimate, president. Thereafter, the party embraced Jim Crow as slavery's next-best substitute, elected a president who imposed segregation on the federal workforce, and remained the chief opponent of racial equality...

Lincoln habitually would tell people he was totally ignorant of a subject which in fact he was quite well versed in, because then they would underestimate him, and when they underestimated him they would fall into his trap. Leonard Swett once said that anybody who mistook Lincoln for a simple man would soon end up with his back in a ditch.

Protecting slavery, Lincoln declared, had become the chief irritant that provoked the Southern states to reach for the solution of disunion.
