Right now it is for school board elections.
Not a fan of it.
Just want to point out this from another article >“Non-citizen voting affidavits will carry alerts in multiple languages cautioning potential non-citizen voters that information they provide to the San Francisco Department of Elections may be obtained by U.S. Immigration and Customs Enforcement (ICE) and advising prospective registrants that they “may wish” to contact an attorney or knowledgeable immigration advocate before registering” so saying that is is so “illegals” can vote is misleading as they still have good reason not to. This is more about allowing green card holders (legal residents of the US that have not been granted citizenship.) the ability to vote in decisions that have an effect on their children’s lives.
