I'd endorse Matt's comments on "symbolism" here, and suggest that calling the Warren issue "symbolic" is just a method of marginalizing minority discontent. Warren is not a symbolic figure. He's a religious leader who mobilizes his flock and leverages his public influence in order to affect electoral outcomes. The most prominent example was the Proposition 8 ballot initiative -- as opposed to, say, the Proposition 8 symbolic logo design contest -- in California. Warren used his power and prestige instrumentally, not symbolically. And Obama is giving him more power, and more prestige, which he will, quite assuredly, deploy in an instrumental fashion. Meanwhile, I'd also note that the people deriding concerns about Warren as "symbolic" are the same people who were dancing in the streets when Obama won the election. When the symbolism mattered to them, they weren't spending a lot of time noting that Obama's basket of policies was really pretty standard for a Democratic candidate and so people shouldn't get exercised over the symbolism embedded in his victory.
