Well, all the
people of color will automatically vote for her. Splitting away votes from Warren/Biden/Sanders and who know who else will throw their hats into that three ring circus. (Sanders and Warren splitting the BSC vote, with, I never thought I'd say this, Biden getting the saner democrat votes.
)
Expect lots of talk of primary rigging, etc. no matter who wins where. (results of Berniebots court case in Florida will determine how much of a factor this will be.)
If she doesn't win, then a sizable chunk of the black vote will sit home on election day 2020.
It may not pan out like that, but someone can feel free to dig this post up come 2020 and either mock me for being so far off base or bask in the luster of prescience.
