Would be a great DNC Chair.  I volunteered for his rally in Nashua, NH and I swear, he is a freakin' rock star.  He really got the crowd fired up.  

Elizabeth Edwards is also a great speaker.  I caught a few of her rally appearances on CSPAN.  I would love to see her get involved too, but sadly, right now, she's fighting breast cancer.  

I think the Edwards' family involvement will depend on how well Mrs Edwards does in treatment.
