Hillary is not going to run.
She will be bitter, but she is not going to run.
And, while I don't like her - I do think its important to note the role she has played in making it possible for a female candidate to run for president. I think when you look at Harris or Warren or Gabbard or Klobuchar the first thoughts most people have are: "What are their positions on X, Y and Z? Do they align with my views?"
I think most people see candidate first, gender second (or not at all). Hillary took a lot of arrows along the way - some justified, some not - to normalize the idea that a female can be president of the United States. Obviously there have been many female role models along the way - but I think Hillary stood out among women by showing she could play the same game as the men in the rough and tumble world - and not just play, but beat them at their own game.
I hope, in time, people recognize the barriers that she helped break. She will fall short of her personal goal of winning the White House - but she played a key role in opening that door.
