Hillary is not running for president in 2020; you can bet on it. She’ll be given a dignified way out (enjoying retirement, fighting for her issues in her own way, etc.), but no donors will support her after the 2016 fiasco. I can’t think of any other candidate, with all that big money and Big Media behind him/her, who would have managed to lose that election. She is just toxic in too many states, and post-election revelations aren’t helping; she’d get far less votes in 2020 (if she’s even able to stand up).
Hillary IS running for president in 2020. You can count on it. She almost won in 2016. Getting the nomination however depends on who else is running.
