Here is my take:
Major fan of her and have been watching her and Fox I guess as long as it been on.
Looks: Well the good looks wagon stopped at her house twice.
Smarts: Got it in spades!
So what happened? As she grew she began to change, her hairstyle, her overall look and I started to notice a haute attitude that grew and became snobby to say the least. Lets remember she went from a junior reporter to the class act and almost the top paid female on FOX in a very short time. Her rating were beating O'Reily on a regular basis.
As I undertand she jumped ship and I think the reason is her ego which by then was huge. I think FOX offered her $25M, but she took $23 and some opportunity for bigger with ratings etc.
She was banking on ME to follow her over to NBC [I use ME to describe her collective fan base). Well why would I go to NBC and its fake news and junk when I have FOX and she is just a 1 hr show. SO no not following her and in order for her to create an all NEW fan base she needs to swing hard and very far left, otherwise she is just another pretty face for an hour or so.
Then there was the Trump debacle! She did not like him and it showed, she was banking on him not winning, but he did and it got so ugly that Trump cut her out of the game and that was a major hit her not being able to bring Trump news.
Loss of fanbase when she left, loss of Trump support, ego of going from $60k to $12M in only a few years, jumping into a far left pond...can she recover?????????
