Probably for the same reason young girls love Kim Kardashian -it isn't what they've actually done or look like, it's what they symbolize.
Hillary is the Great Unfulfilled Hope of Womanhood - no matter how old or ugly or incompetent, or downright mean she is in real life. Just as Obama was the Great Unfulfilled Hope of Blackness. Even attempting to run for office against them is racist, sexist, and just plain rude. :)
Crony capitalists to provide the campaign $$$
Feminists and entitlement army to provide the votes.
May be a tough combination to beat, sadly.
