Proposition 1- Yes. Incredibly simple, and abortion and contraception rights should be codified in the state constitution. Could still be overridden by a federal ban, but that’s the Supremacy clause for you.
Proposition 26- No. If it’s just about permitting online gaming on tribal lands, why are roulette and dice games explicitly added to the permitted games list (page 79, section 19f)? Why only permit civil lawsuits the state doesn’t deem it worthwhile to pursue (page 81, section 19990 b2)?
Proposition 27- No. 10% (page 94, section 19775 a) is an excessively low rate (as you’d expect for a measure funded by gambling companies), as you can see in the rate comparison chart from the tax foundation here. Section 19776 somehow tries to enforce a 15% tax on the individuals who gamble illegally (not the providers) (page 95), except on tribal lands (page 96, subsection e). This would seem to heavily incentivize illegal gambling on tribal lands, even while other portions of the proposition require tribes to surrender their sovereign immunity except for that case (pages 92 and 93, section 19770). Finally, the amendment threshold is absurdly high (5/6ths majority) and likely to be struck down for that reason alone (page 99, section 19790 b).
Proposition 28- Yes. We’ve been gutting arts education in schools for years, and requiring funding for that with mandatory online reporting on uses (pages 106-7, section 8820 g4) is a start to fixing it.
Proposition 29- Yes. Aside from the core issue of expertise, required reporting to the state on infection rates to be posted online would be a significant public health benefit (page 109, section 1226.8 b).
Proposition 30- Yes. While I dislike that a significant portion of the revenues (about 23% between page 117, section 80219 and page 113, section 80205) set aside by the tax would go to reimbursing purchases of new ZEVs (rather than used, or the numerous other worthwhile areas set aside elsewhere in the proposition) (page 117, section 80221 c1), there are still substantial portions set aside for fighting wildfires (page 118, sections 80224-6); funding single and multi-family EV charger installations (page 115, sections 80213-4), and getting more ZEV mass transit (page 117, section 80220).
Proposition 31- Yes. Remove the incentive for companies to target minority communities with flavored tobacco advertising and they’ll stop doing it, naturally decreasing demand over time. With regards to medical devices, I think that the way the proposition references section 104495 (link here) excludes nicotine replacement products registered with the FDA because of subsection 8B, but I could be wrong on that.
