I found this on DKos from an interview today with Edwards campaign advisor Mudcat Saunders:
Norah O'Donnell: Clearly, both Clinton and Obama are courting Edwards'
endorsement. Mudcat, who do you think it's more likely he would
endorse?
Mudcat Saunders: Well, you know, you'd have to ask John that. I got
off the phone with him this morning and, heck, I talked to him longer
than usual. I think today John is really interested in making sure
that his staff is okay because, you know, there are a lot of
passionate people on this staff. But, you know, I can't speak for
John. I can say this that, you know, being a southerner, being a rural
American who's been completely devastated by the trade policies of the
Clintons, I'm going to do everything in my power to make sure that he
does not endorse Hillary Clinton.
Norah: And why is that? That you're going to do everything in your
power to make sure that John Edwards does not endorse Hillary Clinton?
Mudcat: Well, because I believe in the 22nd amendment to the
constitution and I think that this thing is in violation of it.
Norah: Mean having -
Mudcat: Like I said, that when I'm traveling now up through north
Georgia, passing towns and be going through South Carolina and turn
over into the Appalachians and everything looks like, you know,
Sherman went through it but didn't burn thing, I think there is
accountability involved there. For Hillary Clinton to continue to talk
about the unintended consequences of NAFTA -- they weren't unintended,
they were unconsidered. You know, we all heard about the giant sucking
sound when they first started talking about this. I just don't think
the Clintons have been a friend of my people out in rural America.
