California's sanctuary state law is driving a wedge as deep as the San Andreas fault between cities like San Francisco and San Jose.
Momentum is now growing for a so-called "New California" to secede from current day California.
It's called intra-state secession, where one section of the state splits off to form a new state. And Dan Miller with the Texas Nationalist Movement says it's nothing new.
“It wasn't that long ago there was a similar movement in Colorado,” he says. “There's also brewing momentum in New York state to essentially separate New York City from upstate New York.”
But Miller says it's a much more difficult process than trying to secede from the union.
“You actually shrink your power base and make yourself continue to be subject to federal bureaucracy that piles on with 180,000 pages of worth of federal laws, rules and regulation.”
“If you think making a state in the union an independent nation is difficult, start working out the issues related to becoming the 51st state and see how that plays out for you.”
Intra-state secession has happened three times in U.S. history.
Vermont split from New York in 1791. Maine left Massachusetts in 1820 and West Virginia seceded from Virginia during the Civil War in 1863.
