Californians deserve a government that works for them and with them. One that will work to ensure opportunity and justice. We are building a California not for the few, but for all — including those who have historically been left out. We are doing the work to make our state a place for every Californian and all the diversity that makes us strong. Our state will be known as a place where everyone is respected, protected, and connected.
