Group pushes to secede El Dorado County from California, form own state

A group of residents in El Dorado County, California have proposed seceding from the state to form their own independent state called the Republic of El Dorado State.
The group believes they can legally secede by citing provisions in the U.S. Constitution and California's history.
The proposal requires approval from both the California legislature and U.S. Congress, though legal experts doubt its chances of passing.
Activist Sharon Durst is spearheading the effort, arguing El Dorado County is self-sustaining and encroached upon by other parts of California.
Secession attempts are common in U.S. history, though rarely successful.
