This year, Obama appeared before Rev. Al Sharpton’s National Action Network (whose official slogan is “no justice, no peace”) to seek its support. The candidate praised Sharpton as “a voice for the voiceless and . . . dispossessed. What National Action Network has done is so important to change America, and it must be changed from the bottom up.” Given Sharpton’s long career of reckless racial demagogy, it might seem shocking that a mainstream candidate should be seeking his blessing, but in this, at least, Obama was not unique: all of the 2008 Democratic aspirants did so.
