"I think that's between her and her conscience," Edwards said of Clinton's decision. "If she believes that her vote is justifiable, she should defend it. If she believes that it was wrong, she should say the truth about it. … I think she'll get this question over and over and over. It'll be for her to decide what to say. Let's look forward rather than backward."
Looking forward to 2008, Edwards does not want anybody to be unclear on where he stands on the issues.
"Seasoning," Edwards says when asked how he's a different candidate than he was in 2004. "I'm the same human being with the same values, wanting to make sure people in America get the same kind of chances that I've had. But I think there's a maturity and a depth that comes from having been through this."
