LOS ANGELES (AP) — Another attempt is underway to establish California as a separate nation.

A proposal has been submitted to state election officials that would ask voters to repeal part of the state constitution that declares California an inseparable part of the U.S.

Supporters have been cleared to begin collecting the nearly 600,000 voter signatures needed to place the plan on the ballot.

Similar attempts to divide the state or break it off from the union have failed.
