Sparing you a google web search and rummaging around:

• SF Dept of Elections voter info, CA voter info. Candidate statements, arguments for & against propositions.
• SF League of Pissed-Off Voters. Often right but not always… but their analysis can sure help you make up your mind about which are which. Not useful for governor's race: Couldn't get past their (justified) revulsion of Gavin Newsom to say anything either way about John Cox.
• SF Bay Guardian endorsements. Often right but not always… has good analysis for some things, less-so for some other things, making it tough to know whether you agree with them. Not useful for governor's race: Couldn't get past their (justified) revulsion of Gavin Newsom to say anything either way about John Cox. Yes, San Franciscans remember that Newsom was mostly bad as Mayor. (Ha ha ha oh man remember how Care not Cash housed all of our homeless people? ha ha that was so great ha ha oh wait no it didn't do that at all sobs). But say something about the opponent.
• SF YIMBY Action endorsements. All they care about is building more housing, which SF needs. This is useful as a counterpoint to the SF Bay Guardian which is against building more housing. But then it gets weird when they suggest you vote for someone for the City College board because he's for building housing on the nearby Balboa Park reservoir land but the CCSF folks don't actually control what happens to that land‽ So maybe that laser-focus one-issue approach is sometimes counterproductive. Anyhow, when YIMBY recommendations differ from other recommendations, that's a sign you want to look more closely at those issues.
• Alix Rosenthal on CA State offices and props. A mix of endorsements and predictions. She says she's also going to write up SF city things…
• Pete Rates the Propositions Pretty good analysis of CA state props.
• Indivisible SF asked some candidates their opinions on some topics. For the races I looked at, one candidate answered and one didn't. Which might make you think it's not useful for comparison, but I happen to favor the candidates that answered, so I guess willingness-to-respond-to-the-nice-Indivisible-folks is useful voter info?
