I don’t know it.
I cannot speak to her current position since I no longer follow her closely, but I’ve seen articles where she definitely liked Romney and I’ve seen articles where she is clearly unhappy with Trump.
I suppose I have to admit I do not know her innermost thoughts and so I am “guessing” that she has (at least in the past) “preferred” Romney over Trump. Perhaps I suppose too much. But it is not an outlandish assumption. It is a viewpoint which is fairly common around here.
She was pretty gung ho for Trump early on, particularly since Trump was carrying her “hot button” issue “illegal immigration”. Every time she interprets a Trump action as a weakening on that issue she attacks! Her past infatuation with Romney I can only explain by using an analogy with my late mother’s liking of him. Difference between her & my mother is the New York bombast, something my mother disliked inensely but something Ann & Trump share.
I personally have no problem with Anne being critical a good critic is always needed. I think she misinterprets “maneuvering for advantage” as weakening on the issue. She is wrong there. (At least I hope!)
She preferred Romney as the only Republican with the money and organization that could and at that time Romney was anti immigration pretender.
