Conservative bloggers and websites have been flogging it, and now John McCain’s campaign has put its imprimatur on it: a newly disclosed radio interview in which Democratic rival Barack Obama talks about the redistribution of wealth.

The interview, first reported by the Drudge Report, was with a Chicago radio station while he was an Illinois state senator on Sept. 6, 2001.

Obama is talking about the victories of the civil rights movement, and says, “You know if you look at the victories and the failures of the Civil Rights movement and its litigation strategy in the Court, I think where it succeeded was to invest formal rights in previously dispossessed peoples so that I would now have the right to vote, I would now be able to sit at the lunch counter and order as long as I could pay for it I would be okay. But the Supreme Court never ventured into the issues of redistribution of wealth and sort of more basic issues of political and economic justice in this society…. And one of the I think the tragedies of the Civil Rights movement was because the Civil Rights movement became so court focused I think that there was a tendency to lose track of the political and community organizing and activities on the ground that are able to put together the actual coalitions of power through which you bring about redistributive change and in some ways we still suffer from that.”

The entire context of the interview isn’t clear, and the sentiment isn’t all that different from Martin Luther King Jr., who after the voting rights and other accomplishments of the 1960s civil rights movement moved toward greater emphasis on poverty and economic justice.

“What the critics are missing is that the term ‘redistribution’ didn’t mean in the Constitutional context equalized wealth or anything like that. It meant some positive rights, most prominently the right to education, and also the right to a lawyer,” Sunstein said. “What he’s saying – this is the irony of it – he’s basically taking the side of the conservatives then and now against the liberals.”
