If Hillary refuses to be forthright about turning over emails when she was sec of state, I can only imagine what a secretive, locked down administration she would create if she were to become president. This is not a great way to enter national politics, in my humble opinion.

Hardcore voters on the left and right will favor or oppose her regardless. What decides elections is those less ideologically committed swing voters in the middle. I can't imagine her secretive demeanor and refusal to allow a neutral third party to view the emails will help her candidacy. I believe it's an entirely reasonable request that she's refusing, and I think it will give many voters cause for concern. It just doesn't smell right.
