There will never be another John Lewis. In the world of social justice, it is rare for our most prominent leaders to live a long life — think of Martin, Malcolm and Huey P. Newton. Seeing our leaders turn into elected officials is even more of a rarity. John Lewis was able to do both, and become a uniquely revered figure along the way. To those of us doing the work of social justice, Lewis was a freedom fighter and a mentor. To those who work in politics — regardless of party affiliation — he was a highly respected official. To those of us who have dabbled in both, he was a symbol of ultimate balance.
