Richard Norton Smith

Presidents in wartime, embattled presidents, unpopular presidents, they all look to Lincoln. He's their patron saint because no president was more embattled or more unpopular than Lincoln was during his presidency. We think he was born on Mount Rushmore. Not so.

Richard Nixon as a 12-year-old was given a portrait of Lincoln that he hung over his bed. Nixon also justified what would later be seen as abuses of power by comparing America in the Vietnam era to the country during the Civil War.
