Esperanza Tervalon-Daumont and Alicia Garza have this article in New America Media, explaining that the San Francisco Chronicle and the San Francisco Chamber of Commerce have been carrying on a public relations campaign against Instant Runoff Voting in San Francisco and Oakland. The article does not mention the lawsuit against San Francisco’s Instant Runoff Voting system, but that lawsuit is also part of the campaign against IRV. It is called Dudum v City and County of San Francisco.
The same law firm, Nielsen Merksamer, that is trying to overturn IRV in San Francisco, is the same law firm defending California’s top-two election system in the lawsuits Field v Bowen and Chamness v Bowen. Thanks to Rob Richie for the link to the article.
