AOC 

Alexandria Ocasio-Cortez is a name that comes up a lot in reference to up and coming politicians. AOC has not officially thrown her hat in the ring for this race but no one else has either, regardless she is a potential candidate for the role.  

Ocasio-Cortez is extremely popular with many on the left and could garner a lot of support from those Democrats that have only been recently elected into Congress. The old guard is not a fan of Ocasio-Cortez but that might not matter if she plays her cards right.
