Wondering why the left is split in SF’s Congressional race to replace Nancy Pelosi? This is by far the best overview I’ve seen: https://jacobin.com/2026/06/sf-congress-election-chan-chakrabarti

In San Francisco, a Divided Left Eyes Nancy Pelosi’s Seat
Two progressives — Justice Democrats cofounder Saikat Chakrabarti and union-backed city hall veteran Connie Chan — are fighting to advance past the primary for Nancy Pelosi’s congressional seat. Their race has become a referendum on the SF left’s future.

If you live in San Francisco,
there’s a good chance that somebody knocked on your door today from the Saikat Chakrabarti campaign.
An early employee at Stripe, the payments processing company,
Chakrabarti spent $8.8 million of his own money trying to replace Nancy Pelosi in Congress.
Several hundred people fanned out around the city to knock on voters’ doors canvassing for him.
His campaign says they cumulatively visited 5,000 homes per hour.

Abstract: Gravitational-wave (GW) cosmology is currently bottlenecked by the scarcity of electromagnetic counterparts for bright sirens and the systematic uncertainties of galaxy catalogs for dark sirens. We propose a purely gravitational resolution using the Integrated Cosmological Memory (ICM)-the cumulative GW strain encoded in the spacetime geometry of an expanding Universe. While the GW transient emitted by the source provides the luminosity distance, the ICM accumulates a mathematically distinct integral of the cosmic expansion history. We demonstrate that extracting both observables from a single binary merger completely breaks the distance-redshift degeneracy within the gravitational sector. This establishes a novel, catalog-free dark siren framework for third-generation GW detector networks. Crucially, the resulting constraints on late-time dark energy are only weakly sensitive to the local expansion rate, providing a robust cosmological probe that can potentially mitigate the impact of the H0 tension.

"Until now, the record for most spending per vote was held by Mayor Daniel Lurie, who paid $156.14 for each of his first-choice votes in the 2024 mayoral race. But there’s a big difference: Lurie won."
(He had much worse opposition! It was a terrible field.)

$211 per vote: How Saikat Chakrabarti spent $8.8M on his congressional run
Connie Chan spent $25.09 per vote. Scott Wiener spent $61.24. Saikat Chakrabarti spent...a lot more than that.

This is the kind of unity we need to see among left-of-center candidates—everyone not on the billionaires' team. Like Saikat, I'll support Connie in the general election. I won't hide my disagreements with her, but fortunately most of them are much less relevant to federal office.
