I don't think this email nonsense is a complete non-story, like some do, but it's not going to derail Clinton's candidacy. The problem is that it reinforces the negative feelings people already associate with her and her husband, but that alone isn't enough to mortally wound her campaign. Bruise, yes, but no more than that. That this is happening in March of 2015 and not 2016 is on whole a good thing for her, since it's more than 18 months to the election. She'll be fine.
Until something else comes up and something else and something else.
