In 1864 Lincoln apparently considered replacing Hamlin with a War Democrat in order to get more votes, partially out of the fear pre-Sherman's March that the North was sick and tired of the war and wanted out. Among the various considerations were Andrew Johnson (a native of Tennessee and Military Governor there) and Benjamin Butler (New Orleans military governor). Assuming that Lincolns assassination goes off as OTL, what would either of these men handle the post war situation? Obviously Booth and Co. would be hanged, but would either of these men try anything like that on the Southern Generals or the more rabid Fire Eaters?
