Personally I don't think it is a good idea to base your opinion in any PM by what they say in public what their taste in music is like. They will always choose someone that is fashionable at the time. People should base their opinion in a PM by what they do to help the country and its people, and at the moment she hasn't done anything as yet.
I agree 100%. (Except I'm pretty sure she's genuinely a Swiftie.)
