This only makes sense when I realize that to conservatives, it’s an identity. They think it’s an identity that Taylor Swift should have because she’s (presumably) white, popular, rich, good looking, Midwestern, Christian, etc.
To them politics is not about ideas, or policies, or problem solving, or good governance. It’s all about identity.
I can clarify. I am pretty sure it was mentioned to position her outlook in a similar spot on the overton window as the conventional mainstream liberal representatives, so that it is clear that she’s aligned with other socially liberal and fiscally colonial oligarchs.
