Los Angeles County
The nearly 10,000,000 people living in Los Angeles County could not survive without the nearly 2 billion gallons of water supplied by the other 56 counties in California.
Without the water supplied from other counties. Los Angeles would become a ghost town.
Because L A County controls the state legislature the residents of the other counties have virtually no say ,
When all of the counties were represented in the Califirnia State Legislatire they had a voice, but when the Supreme Court ruled that the state's practice of equally representing the counties was unconstitutional the counties lost their voice.
The two U.S. Senators don't represent the people of the entire state, they represent the people of LA County.
