(By BILL BARROW Associated Press) – Joe Biden is reorganizing his top presidential campaign leadership after a fourth-place finish in the Iowa caucuses. He’s elevating Anita Dunn to a role that effectively puts her in charge of his third White House bid, just days before the New Hampshire primary.

Biden had spent months leading national polls of Democratic primary voters. But he’s faced persistent doubts about the quality of his campaign operation in Iowa and New Hampshire, the first two states in the presidential nominating process. And his campaign fundraising has lagged behind other leading contenders.
