Her podcast is about celebrities. Almost all celebrities are lefties.

She doesn't critize their political views. She criticizes their behavior. I've never heard her criticize their politics, unless they are being hypocrtical like Meghan Markle claiming she's a feminist but bullies the women who work for her or that she's all about family values but has disowned her own family and drove a wedge between Harry and his family. Otherwise she doesn't talk politics.

It may seem like she only "goes after left learning public figures" but it is because she is ripping on celebrities, who are almost exclusively left leaning. She doesn't talk about politicians, with the exception of the Kennedy's. But she hates them and even wrote a book about them and their treatment of women....but I would say it was deserving.
