What is remarkable is the extent to which this kind of patriotism—and much of the mood surrounding the convention—is rooted in black traditions of political and religious rhetoric. In ways small and large, the lifeblood of the Democratic National Convention was the black church. You saw this, in a literal way, with the stream of black politicians and black religious leaders who took the stage. The Rev. William Barber, the North Carolina preacher and head of his state’s NAACP who founded the “Moral Mondays” movement, gave a speech that was emblematic of the language on display, a language and cadence drawn from the traditions of the black church. “Now, my friends, they tell me that when the heart is in danger, somebody has to call an emergency code, and somebody with a good heart will bring a defibrillator to work on the bad heart,” said Barber in his thundering address. “[W]e are being called like our foremothers and fathers to be the moral defibrillators of our time. We must shock this nation with the power of love. We must shock this nation with the power of mercy. We must shock this nation and fight for justice for all.”
