Our Election Central team has been tracking developments all day in the superdelegate primary. Obama has been working them especially hard, trying to use the momentum from his Tuesday showing to peel off a few more undecideds — with mixed success. We’ve got the rundown here.
Late Update: Greg Sargent interviews Obama’s chief superdelegate whip, Rep. Melissa Bean (D-IL), about the state of play, and she makes a surprising assertion: Not only has Rev. Wright not posed a problem for superdelegates, but it’s actually encouraged them to come out for Obama sooner. Surprising and counterintuitive. Count me as skeptical.
