WGBH's  Callie Crossley ( @CallieCrossley) and Tulane Assistant Professor  R. Blakeslee Gilpin discuss the confederate flag debate, and shocking new poll numbers. 

The fight over the confederate battle flag is intensifying, with South Carolina lawmakers taking up the issue and the American people weighing in.

"Nobody understands history," said Crossley, "or the story of the Confederate Flag." 

"This is the symbol that all of the white supremacist groups use."
