Flubbermouth Joe can be partially ignored, for now. If, he becomes a serious contender, simply ramp up the investigation into the Ukraine scandal. I understand the Ukraine AG has reopened it. Biden family profited from the ex pro-Russian Ukraine president (now in exile in Russian). Add, their work in China where the family profited again.
Biden said he got a phone call from Margaret Thatcher, recently, she was worried about Trump as president. I suspect, the late Baroness Thatcher called to tell him he's being recalled. There will be a warm reception for him. But, she won't be attending.
