As President Obama prepares tonight's farewell speech, his approval ratings are well above many ex-presidents and much higher than Donald Trump's. He's bound to go down in history as the first black president of a nation with a legacy of slavery, Jim Crow and other forms of racial discrimination. We ask activists and historians about the example he and his family have set during the past eight years. Are millions of black people better off because of his policies? What's the state of race relations after Barack Obama's two terms in the White House?
