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.
Entertainment requires a lot of traveling and contact with lots of different people. That lends itself to leftwing viewpoints and thinking.
This is true to an extent I think, however it’s different traveling and wanting to experience another culture vs business. If the people you surround yourself with are there to support you and reflect your viewpoint back at you (Ted Nugent being an extreme example) it’s more of an echo chamber than an education.
