Sister Souljah 2.0

This Associated Press article says Barack Obama told the NAACP convention that blacks need to take more responsibility for their own actions. This is the same sort of message that irritated civil rights careerist Rev. Jesse Jackson, causing him to fantasize off-camera but on-microphone about castrating Brother Obama.

It occurs to me that this message is Obama's version of a Sister Souljah moment, done in slow motion over time in a series of venues. Wikipedia says such acts of repudiation are:

designed to signal to centrist voters that the politician is not beholden to traditional, and sometimes unpopular, interest groups associated with the party, although such a repudiation runs the risk of alienating some of the politician's allies and the party's base voters.

The term originated in the 1992 presidential campaign of Bill Clinton. It refers to Clinton's repudiation of hateful, racist anti-white material performed by African-American hip-hop entertainer Sister Souljah.
