Lincoln wasn't an abolitionist.
Nor were abolitionists even a strong enough demographic for politicians to pander to in the first place. Genuine abolitionists were few and far between.
He was. How do I know? Because he was a republican you ******* dummy! He didn't want to start a war over it! He didn't have to ether because the confederate democrats did it anyway.
"I will say then that I am not, nor ever have been, in favor of bringing about in any way the social and political equality of the white and black races; I am not nor ever have been in favor of making voters or jurors of negroes, nor of qualifying them to hold office, nor to intermarry with white people. I will say in addition to this that there is a physical difference between the white and black races which I believe will forever forbid the two races living together on terms of social and political equality. And inasmuch as they cannot so live, while they do remain together there must be the position of superior and inferior, and I, as much as any other man, am in favor of having the superior position assigned to the white race." - Abraham Lincoln, the great abolitionist
