Where do you get that she is a staunch liberal? I see in Wikipedia this mention

> Writing in The Guardian, Moira Donegan called Weiss a "professional rightwing attention seeker" and disputed her claim that social media's influence had led to a hostile media environment for conservatives.

In addition, her employment history outlined in Wikipedia seem to be filled with fairly conservative outlets or stints (WSJ, Die Welt, NY Times stint cited as an effort to bring in more diverse ideological views). Nothing wrong with that necessarily, just pointing it out as contradictory to the claim that she's a staunch liberal.
