Good morning.

Let’s turn it over to Conor Dougherty, a technology reporter based in the Bay Area.

When tenants started collecting signatures to expand rent control in Silicon Valley earlier this year, organizers knew that they were in for a tough political fight with landlords. Now, with the election fast approaching, that fight is heating up.

On Thursday, tenant activists gathered outside the Hayward regional office of the California Apartment Association, a trade group for landlords, to protest what they describe as a deceptive mailer that the association sent out to urge voters to reject the various rent control measures on the state’s November ballot.

The mailer in question was emblazoned with the logo of California’s nonpartisan Legislative Analyst’s Office, causing groups favoring rent control to charge the C.A.A. with “impersonating” a government agency. Organizers said they plan to file complaints with the California Fair Political Practices Commission.
