Actually, there was outrage over Sharpton and Jackson.
Outrage from whom? They sat on the stage with all the other Dem candidates for President and were treated with the respect and deference accorded everyone else. They were equals. I didn't see any other Dem candidate become outraged that Sharpton was even being considered to be President or sitting on the same stage with them. In fact, they joked with him and the MSM fawned over him. Al and Joe Lieberman joked with one another.
