Nancy Pelosi's retirement has turned CA-11 into something far more entertaining than your average congressional race — it's become a full-blown Democratic civil war, complete with ghosted endorsements and political backstabbing that would make a Bravo producer weep.

Here's the setup: Saikat Chakrabarti, the architect behind AOC's legendary 2018 upset of Joe Crowley and co-author of the Green New Deal, is running as a progressive insurgent for Pelosi's open seat. On paper, this should be a layup for a progressive endorsement from his old boss. In reality? AOC won't even say his name in a positive sentence.

When asked directly about Chakrabarti's campaign, AOC didn't just decline to endorse — she completed an entire interview without offering a single kind word about the man who essentially built her political career. This, while she's happily endorsing progressive challengers in Illinois and New Jersey.

The backstory matters. Chakrabarti left (or was pushed from) AOC's office in 2019 after a series of inflammatory tweets, including calling Native American congresswoman Sharice Davids — a moderate Democrat — a "white supremacist." AOC publicly called the remarks "divisive" and distanced herself fast.

As one SF resident put it bluntly: "Saikat's entire brand is built on attacking Democrats instead of attacking Trump. The absolute last thing AOC needs right now is to endorse a friendly-fire liability."

Another local observer was even more direct: "Maybe she saw something in him when he worked for her that she didn't like. It's not surprising that he frequently refers to his time with her — he has a lot to gain from linking his name to hers."

From our perch, this race reveals something important about the progressive movement's maturation — or lack thereof. The "rotating villain" strategy that some candidates are calling out, where party leadership always finds one Democrat to take the blame for blocking popular legislation, is a real phenomenon worth scrutinizing. But Chakrabarti's particular brand of scorched-earth progressivism, where moderate Democrats are smeared as segregationists, isn't accountability — it's self-indulgence.

San Francisco deserves a representative who can actually build coalitions, not just burn them down on Twitter. Whether that person emerges from this crowded field remains to be seen, but the fact that even AOC — the queen of progressive insurgency — is keeping her distance from her own former chief of staff tells you everything you need to know about the limits of purity politics.
