What political changes during the civil war helped contribute toward its end?

I was wondering how politics in both the North and South helped contribute toward ending the war. Also, were there any societal influences that helped end the war, too?|||1. That Britain and France did not get involved. If they had supported the South, it might have changed the war.


2. 1864 Lincoln won reelection by only a small margin. If he had not won, the North might have ended the war.


3. Sherman's capture of Atlanta saved Lincoln's campaign.


4. Lincoln's second Inaugural Address - pushed for end of war.
