That's what I think. Elizabeth Warren lost her own home state, Massachusetts, to Biden. She actually came in third behind Biden and Sanders. I have a feeling that's it for her and I will not be surprised if she soon drops out. Considering her feud with Sanders, if she does drop out I think she will join the others and throw her support to Biden.
At this point I would like to see them all drop out and start helping Biden do everything that can be done to beat Trump and get a Democrat majority everywhere - Congressmen, Senators, Governors, state legislatures . . . right on down to school boards.
As for Trump, McConnell, Graham, Rubio, et all, I hope:
