The unhappy California wants to be called as a separate country for they had have enough under Trump's administration, many campaigns are planning to protest for referendum like the, Yes California Independence Campaign that is struggling for holding election in 2018 to make California an Independent state.

The campaign believes in California's autonomous power that can improve its own aura and can perform well without the interference of Trump presidency and they said, "As the sixth-largest economy in the world, California is more economically powerful than France and has a population larger than Poland. Point by point, California compares and competes with countries, not just the 49 other states."
