More Americans lost their lives in the Civil War than in any other war. Every decision weighed heavily on Lincoln, which had visible effects on his appearance. 1864 was the first election held during wartime since 1812. Allowing the election to be held at all was a crucial, frankly underrated, decision by Lincoln. Many believed the election should be postponed, but Lincoln insisted it was necessary to preserve our democracy, even if he might lose. But hey, he's the greatest president of all time for a reason.
