She was doing so poorly, it was the only move she had. I don't know who she'll endorse because she's had issues with Sanders and she too far to the left for Biden.
One time my 1st husband went downtown to a City Counsel meeting and asked them what 'back door deals' they were creating instead of helping him with his problem. You could of heard a pin drop. Then they jumped up and agreed to help him with anything he needed. That made me realize how the political game is played.
