Aside from the message being sent, remember that Cali is a red state being held hostage by the coastal outliers. Between voting roster cleanup and deportations, this might cause the state to become a toss-up in 2020, as opposed to being a solid blue. Either way, it destabilizes and demoralizes the left since they have to focus on damage control rather than recruitment, and creates the possibility of the democrats further exposing their true selves. Not a strategist, but a thinker. I could be wrong.
