I'm officially running for Governor of California. My priorities: -Single-payer health care - Ban corporate PAC money - Build homes you can afford - Close tax loopholes for corporations & billionaires - Lower electric bills by 25% - Make CA a top 10 education state

I’m proud to endorse Jake Levine for Congress. We can turn California around if we elect the right leaders like Jake who don’t follow the old performative actions of the political old guard. Jake is a doer who took immediate action to help Palisades & Altadena fire victims & will bring that same leadership to Congress.

For decades, the grid assumed predictable industrial load. Aluminum smelters. Factories. Now, agentic AI changes that. Compute demand could be elastic — shifting across hours, prices, even RTO boundaries — and classifying its own urgency in real time. Explore the implications in our new Halcyon blog, Agentic Elasticity, by @jacobgrindal + @NatBullard: hubs.la/Q045GhM70

In certain circles, Democrats seem confident that you have to fight fire with fire to beat MAGA: be a strident jerk, all caps tweeting, get angry, etc. Seems worth pointing out that two rising stars of the last 12 months, Mamdani and Talarico, both seem really nice.

Solar keeps getting cheaper, faster, and better. Balcony solar is fantastic—unbox it and hang it up. Any politician who opposes this technology is either ignorant or is beholden to utility monopolies. As governor, I'll unleash solar's full potential. canarymedia.com/articles/solar…

Uhhh... this is quite a tone shift from the Trump admin 👀 "Interior indicated in its statement that it considers solar part of the admin’s ongoing efforts to ramp up domestic energy production, which is needed to power energy-intensive data centers..." subscriber.politicopro.com/article/eenews…
