Much more than 'First Lady'. With Kamala goofy and terminally STUPID, Jill has essentially assumed the seat of Vice President. In fact, with Biden cognitively incapacitated, Jill may be acting as POTUS much more than anyone realizes.
Think about it. If I was Soros or Obama and I wanted to get something done, would I talk to Jill or Joe? Foreign leaders will not even talk to Joe. Because they know he has no power, and he will forget whatever is said an hour later anyway.
The seat of power in the White House is Jill. Because Joe is unable to look after his own affairs, it will be Jill who decides his future. And it seems clear that she intends to hang on to power up until the very hour Joe strokes out.
