If Biden runs the real pressure on Hillary will come from the Obama Justice Department. Her legal problems regarding violation of national security laws is just the prod. If she doesn’t get the message and drop out, the FBI will do a serious investigation of the bribes she laundered through Bill’s speeches and her phony foundation while Secretary of State. She can keep the money or be the Democratic candidate. She can’t do both.
I suspect she will ultimately drop out for “medical reasons” but judging by prior Clinton campaigns she will have no trouble getting cesspool-filthy going after Unca Joey.
If anyone could have stopped the Clintons, they would have by now.
Hillary will fight to her death.
