Not only do the Edwards have lots of stuff on their plate right now, Elizabeth used to be a DUmmie but she ran away when they showed her their true face.
Even if they had a link to John Edwards, which they did at one time, why would Edwards be inclined to listen to them at all after that? Even he has to know most of their members are tombstones so that's like maybe 5,000 votes? What was the last Dumpster Dive stats?
Anway, the point is, the DUmp is small potatoes.
