What if Stephen a. Douglas has some how won the 1860 election? I am not sure how he would have reacted to secession. There is a possibility that he would have allowed the South to leave without a war. The problem being Douglas probably would have die at about the same time as he did in June of 1861. It does not seem likely that Vice President John C. Breckenridge would have still been Vice President in June of 1861. I am assuming Breckenridge would have resigned before then and cast his lot with the South. I would have no idea who Douglas would have had as a Vice President when Davis died in June of 1861, so it is difficult to know how his successor would have dealt with the Confederacy.
