There is probably zero chance it will happen but I think the best choice for Clinton politically and America directly would be to nominate John Kerry as VP. Outside of her Husband, he is likely the best qualified man to fill the role of VP. To me, the best argument for electing Hillary from a non-policy wonk point of view is that she is clearly superior to Drumpf in terms of being ready, having the proper temperament, understanding the job, and will need no or very little on-the-job-training. These topics are not arguable. Why not further emphasize the Democratic party's readiness by installing someone whose been there since 1984, respected worldwide, and qualified. His age is a factor.
