DIVERSITY PROBLEM: President Barack Obama’s team is looking to hire more African-Americans, a search that has stirred a debate among black Democrats about Obama’s record on diversity and its implications for his reelection. “The race to stock up on black talent is a welcome development among Washington’s African-American power elite — and one that critics say is three years late in coming. The cynical take, offered up by black Democratic sources outside Obama’s camp: The president and his aides have focused their attention on hiring more African-Americans because they are worried about black turnout on Election Day. . . . The excitement of the 2008 campaign is gone, this aide said, and African-American voters haven’t seen much improvement on issues such as an unemployment rate about double that for whites.”
