She REFUSED to endorse anyone when she withdrew. I think she will wait awhile and use her endorsement potential as a carrot to both bernie and biden to see what leverage that power will bring her. Don't you? Folks assume she will endorse bernie but apparently lately their relationship has frayed around the edges. Her endorsement might bring along with it some or many of her supporters which will accrue to the benefit of bernie or biden. So another politician will play the game to see what's in it for her. That is not a criticism. When you have power you want to use it judiciously and not randomly wantonly promiscuously. Stay tuned.
