Nah, this is just the No True Scotsman fallacy. San Francisco is FAR more left in their politics than most of the nation. For example, the new mayor described himself as:

> As a lifelong Democrat and San Franciscan, I am running for mayor to turn around the city I love

London Breed, the mayor before, was endorsed by explicitly Democrat or nonpartisan individuals (including Kamala Harris)

We could go on. What's ironic here is that this comment just reveals how disconnected this form of left wing politics is from the larger nation. They call even examples of the politics of their own "right wing" because they're so radically left
