That's true of most presidents though. And considering he was at war with half the country, it's not surprising that people he was at war with would hate him.Abraham Lincoln was probably seen as one of the worst presidents during his term.
I don't think it immortalized him, getting rid of slavery is what did that. And I don't think his shortcomings were wiped away either. Despite what is happening in the world today, I still believe that people want to see the best in people and that's why mistakes get minimized when people have done great things.His assassination made him immortalized. Any of this shortcomings were wiped away.
