It's hard to tell. I get the impression that a lot of Teen Vogue readers are actually basically right wing haters, as a conservative that's how I learned about them. But "thought leaders" like influential left wingers on social media and YouTube probably read them too and disseminate their takes.
Yeah I can't imagine conservatives are popular among most young people these days. Hard to be taken seriously when the current Republican leader is a convicted rapist.
Some conservatives are pretty conservatives but when it comes to commentators that aren't that young, they definitely aren't tapped into what young people are actually paying attention to.
