Quick take is that if she couldn't be considered as a good enough candidate this go round to challenge Hill, she shouldn't try to oust the guy that just beat Hill.
I also think that the Bernie and Donald support this year shows that both parties should rethink, at least temporarily, how they decide who is next and the running of candidates because it's their turn is the wrong approach. The public seems to be sick of it and ready for a new approach, imo.
