Billy Richardson is set to endorse Obama in Oregon today. This is sure to help with the all important Hispanic vote in Pennsylvania, Indiana, and Oregon. No doubt his endorsement will also ring in many Philadelphian’s ears a month from now when they vote (and as soon as most of them figure out who the hell Bill Richardson is and why they should care who the governor of New Mexico thinks they should vote for).
Snark aside, I do think this is a sign of what Barack’s efforts this week are achieving. A major target of his speeches (especially the penultimate More Perfect Union) were the undecided superdelegates, since his popular delegate lead is nearly insurmountable. They are beginning to trust him on defense — specifically his own defense.
