Lincoln's hopes for passage of the amendment rely upon the support of Francis Preston Blair, a founder of the Republican Party whose influence can ensure that all members of the western and border state conservative Republican faction will back the amendment. With Union victory in the Civil War seeming highly likely and greatly anticipated, but not yet a fully accomplished fact, and with two sons serving in the Union Army, Blair is keen to end the hostilities as soon as possible. Therefore, in return for his support, Blair insists that Lincoln allow him to immediately engage the Confederate government in peace negotiations. This is a complication to Lincoln's amendment efforts since he knows that a significant portion of the support he has garnered for the amendment is from the Radical Republican faction for whom a negotiated peace that leaves slavery intact is morally unacceptable. Unable to proceed without Blair's support, however, Lincoln reluctantly authorizes Blair's mission.
