Here is the problem with that bit of nonsense. Her ratings are NOT going down, they are going up and she is now beating O'Reilly fairly regularly (he had been the previous cable news ratings king).
Here is an article from only yesterday:
Friday Cable Ratings: Megyn Kelly #1 in Demo and Total for All Cable News

The idea that Trumpster boycotts are hurting her ratings are laughable.
From September the 18th:
Thursday Cable Ratings: Megyn Kelly #1 in Demo for All Cable News

Here is another article from a couple weeks ago noting her trend upwards in the ratings:
Megyn Kelly's ratings soar despite Donald Trump's tweets

Trump's rage tweeting and his followers whining and crying are having exactly no negative effect on Megyn's ratings. It only shows that "the Donald" and many of his fans are a bunch of crybabies. And Trump's flailing and blathering about O'Reilly won't have the slightest effect either.
Sounds like she is using Trump’s name to get ratings.
