Not sure what her plans are. She is leaving Congress in Jan.
But, I have no doubt she loves this country and she is not leaving politics. She is positioning herself for a run for some higher office. I do not think she is putting on an act or posturing for attention. I think she was badly treated by RATS in DC and she is taking some parting shots. She would be very popular in a liberal and moderate GOP state like Hawaii. She could be looking at a Senate seat or Governor. She does seem oddly unpopular with establishment RATS though. If she moved more to the right on some issues, she could be a MAGA candidate, but she is currently too liberal and carries some liberal baggage.
If I had to guess, with her being so easy on the eyes, I see her at FOXNEWS as a liberal voice. She is not well liked at CNN. Of course potential shakeups at CNN could make her a popular host on CNN, her being a more common sense liberal and all.
