Here's something you don't see every day in San Francisco politics: a straightforward, common-sense reform that both Nancy Pelosi and Mayor Daniel Lurie can agree on.

The proposal is simple. If you serve two full terms as mayor or supervisor, you're done. No comeback tours. No decade-long sabbatical followed by a triumphant return to the same seat you warmed before. You had your shot — now let someone else take a crack at it.

Currently, SF's term limits have a loophole big enough to drive a campaign bus through. Officials are limited to two consecutive terms, which means they can technically cycle in and out of the same office indefinitely. It's the political equivalent of "we were on a break." The new measure would impose lifetime term limits, permanently barring anyone who's served two full terms from running for that same office again.

This is exactly the kind of structural reform this city needs. San Francisco's political class has a habit of treating elected office like a revolving door — or worse, a personal fiefdom. Career politicians build entrenched networks of allies, donors, and bureaucratic loyalists that make them nearly impossible to unseat, even when their track record is mediocre at best. Lifetime limits force fresh blood into the system and make incumbents actually accountable during the time they have.

Will it solve all of City Hall's dysfunction? Obviously not. But it addresses something fundamental: the concentration of power in too few hands for too long. When the same faces keep appearing on your ballot cycle after cycle, democratic competition withers. New ideas don't get a hearing. And taxpayers get stuck with leaders who are better at winning elections than running a city.

The bipartisan endorsement here is notable. When figures as ideologically different as Pelosi and Lurie both back a governance reform, it suggests the problem is obvious enough that even San Francisco's fractured political landscape can see it clearly.

Voters should take this one seriously. Two terms is plenty of time to make your mark — and if you haven't by then, that's the point.
