During the Lincoln-Douglas debates, U.S. Senator Stephen Douglas (D-IL) said, “If you desire negro citizenship, if

you desire to allow them to come into the State and settle with the white man, if you desire them to vote on an equality with yourselves, and to make them eligible to office, to serve on juries, and to adjudge your rights, then support Mr. Lincoln and the Black Republican party, who are in favor of the citizenship of the negro. For one, I am opposed to negro citizenship in any and every form. I believe this Government was made on the white basis. I believe it was made by white men for the benefit of white men and their posterity for ever, and I am in favor of confining citizenship to white men, men of European birth and descent, instead of conferring it upon negroes, Indians, and other inferior races.”. Douglas became the Democrat Party’s 1860 presidential nominee.
