Look, I understand the Benghazi issue, soup to nuts.
I just think that anyone who is motivated to vote by it is already on board, and that VRWC attacks on Hillary over it are a motivator for her voters to show up.
It’s a prudential judgement, not a value one, and of course YMMV.
I’m glad you are informed on the issue, but energizing the base is still a factor.
This weakens energy for Hillary and builds massive energy for Trump.
