Saikat Chakrabarti finished third in the CD-11 primary with 18 percent of the vote. Within two weeks, he'd converted his campaign into the SF Solidarity PAC and redirected over 250 canvassers — including many he'd hired specifically to knock on Chinese-language doors — to work for Supervisor Connie Chan's general election fight against Scott Wiener.

The move is Chakrabarti's answer to the central question hanging over every well-funded progressive who exits a race: where does the infrastructure go? In this case, the answer is Chan — and the retooled field operation may hand her a meaningful organizational advantage in November against a candidate who beat them both in the primary.

On June 9, Saikat Chakrabarti sent an email to his campaign staff, according to Mission Local, which obtained the message. The email announced that his campaign was "transitioning campaigning operations into a new entity that will continue field work in support of the Connie Chan campaign." Staffers who wanted to stay on were told their role would continue through July 10.

Two days later, on June 11, Chakrabarti formally converted his campaign committee into the "SF Solidarity PAC," a political action committee that can spend on behalf of other candidates. Filing the paperwork made official what the email had already set in motion.

The field force being handed to Chan is not trivial. During his primary run, Chakrabarti built what he described as "the largest field campaign in U.S. congressional race history" — more than 250 canvassers, with a significant number paid specifically to reach Chinese-speaking voters in the Sunset, Richmond, and other neighborhoods where language access is a competitive factor. Some portion of that team is now knocking doors and leafleting the city for Chan, according to Mission Local.

Chakrabarti had telegraphed the move months before the June 2 primary. Campaign spokesperson Tiffaney Bradley told the San Francisco Standard in April that "if Connie wins the primary, Saikat and his entire team will support her." He largely held fire on Chan during the campaign while training attacks on Wiener, a pattern that left little ambiguity about where he'd land if he lost.

What remains unclear is the money. Chakrabarti, who became a centimillionaire as an early Stripe employee, put roughly $10 million of his own money into his congressional bid. How much of that remains in the campaign account — and whether he will inject new funds into the SF Solidarity PAC — is unknown. Mission Local reported that Chakrabarti did not respond to requests for comment on the PAC's plans or finances. He could be spending down whatever is left, or he could be willing to put more in.

The general election matchup pits Chan against Wiener, who finished first with 41 percent to Chan's 30 percent in the June primary. Wiener enters November as the clear frontrunner, backed by both the institutional Democratic establishment — including a late-primary endorsement from Speaker Emerita Nancy Pelosi that went to Chan — and substantial tech-aligned fundraising. Chan finished second, earning her a spot in the general but trailing significantly.

Whether Chakrabarti's reconstituted ground game materially narrows that gap remains to be seen. The SF Solidarity PAC's canvassing initiative is set to run through July 10, suggesting this first phase is time-limited — though whether it extends into the fall campaign isn't clear.

What Chakrabarti demonstrated in the primary is that he could build a large, multilingual field operation quickly. The question for Chan's campaign is whether that infrastructure, now running under a new banner, can be leveraged past the July cutoff and into a November where she'll need every organizational advantage she can find.

Chakrabarti told Mission Local in April, when asked what he'd do if he lost: "I'm gonna keep working to make this movement happen. This is what I want to dedicate my life to." The SF Solidarity PAC is, apparently, the first installment.
