Yes, very likely, possibly as soon as 2020.
History: The state of West Virginia set a precedent in 1863. Article 4, Section 3 in the U.S. Constitution specifies how folks may go about, in effect, seceding from one state to create another.
In 1861, when Virginia took the side of the Confederacy, some folks in Virginia drew a line and declared their independence just as the Founding Fathers had done in 1776. In view of the ‘insurrection’ of Virginia, and insofar as the folks that petitioned President Lincoln demonstrated their ability to govern, statehood was granted and voíla, a new state was formed.
Introduction: Folks in California are replicating that effort and they have made headway. They drew a line separating rural counties from coastal cities in the state. On January 15, 2017, they took the first step towards creation of a new state, they published their Declaration of Independence.
Article 4, Section 3 specifies next steps to be taken to create a new state*. The second step is to file Grievance with the legislature of the existing state, California, stating their wish to secede. To date, the New California folks have appeared in the California legislature to file grievances ninety times. They will file five more grievances by December 2019 and at that point, the California legislature may approve the request. They actually may for reasons I will not specify here.
In the event they do not approve the establishment of New California as a separate state, President Donald Trump may declare the state of California an insurrection, which would move the consideration of establishment of the second state to the US Congress. Current grounds for this declaration exist.
New California has established it’s ability to govern. It has a Constitution, it has a legislature, a judicial system and former Governor of Texas, Rick Perry has been appointed interim Governor.
This is a remarkable historical moment. I will keep you apprised of the progress of the establishment of New California as the 51st state in the United States of America.
* Not all conditions that are required for the establishment of a new state are specified in this post.
