I could easily imagine her as either conservative or liberal or somewhere in between or somewhere outside of that whole spectrum. I can't imagine that she is a Trumper.

I expect that her reason for not sharing her political beliefs is at least somewhat selfish. She has fans across the political spectrum, different segments of whom would certainly be upset by any political position she espoused. It could even be that she's concerned about fans being angry and violent depending on what her views actually are.

Regardless, the fact that she doesn't use her popularity to influence politics makes me respect her all the more. I my opinion, it's both a smart decision for her, personally, and shows moral character.
