Superdelegate alert: Obama picks up endorsements from Reich, Nunn and Boren

HAVERFORD, PA.–Sen. Barack Obama (D-Ill.) picked up three solid endorsements on Friday, from former Clinton Labor Sec. Robert Reich and former Senators Sam Nunn and David Boren.

None of them are superdelegates, but they are influential enough to send a message to those who are truly wavering. Bookends: Reich comes from out of the progressive left, and Nunn, from the right of center wing of the Democratic party.
