Let's say Lincoln loses in November to a Democrat who supported their platform of peace with the Confederacy (i.e. not McClellan). However in this timeline, the war has happened like it historically did (Sherman took Atlanta, Grant is trying to take Petersburg, etc.). Can Lincoln defeat the Confederacy before the inauguration of his successor in March? If not, but the Union still achieves the successes they historically did by then (cutting off Lee and the Confederacy's last port in Wilmington) will Lincoln's successor still try to make peace with the Confederacy? Finally, if the Confederacy is still defeated, how will Lincoln's legacy and Reconstruction be affected? I understand Lincoln losing the election in this scenario is unrealistic, but that's why this is a hypothetical.
