if Sacramento is as conservative as you say, why weren't they included in the New California plan?

Because it is the government seat. It would be impossible, legally speaking, to create a new government and include the land owned by the present government (the capital). The proper way to take care of the problem is through the will of the people, all of the people, not the fraudulent legal system, and not the "majority" through creative gerrymandering. They are attempting the wrong solution, thus they must fuck millions of people in the process. It is a selfish and short sighted solution, that accomplishes a victory condition for the wrong side.
