People have different ways of venting their post-election anger. Some take to the streets or let loose on social media. In California — where almost 62 percent of the voters picked Hillary Clinton over President-elect Donald Trump — they're talking leaving.
As in getting out. Splitting up. Seceding.
And, yes, they're serious.
Shervin Pishevar, an Iranian-American Silicon Valley executive and entrepreneur, took to Twitter after the election, vowing to fund a campaign to launch California as a new nation. It will be called, Pishevar says, New California. Several other tech types have tweeted they'll join the movement.
"It's the most patriotic thing I can do," Pishevar, an Iranian-American Silicon Valley executive and entrepreneur from Sherpa Capital and Hyperloop One, told CNNMoney. "The country is [at] a serious crossroads."
Others in Cali, even before the election, have pitched the need to break up with Uncle Sam.
The Yes California Independence Committee (at YesCalifornia.org) filed for nonprofit status in 2014. It is demanding "the liberation of the people of California from its captors." It's not quite as violent as it sounds. "We explicitly reject conduct or speech inciting open rebellion against the American government," the group says on its website. Yes California got more than 15,000 new likes to its Facebook page last week, up more than 4,200 percent.
Still, talking breakup, as in all matters of the heart, is a lot easier than actually breaking up. The whole idea of secession was squashed more than 150 years ago in a little thing called the Civil War. Though some states have talked walkout since then — Texas (the Texit!), we're looking your way — any state who seriously considers secession runs up against a wall bigger than the one Trump says he'll build on the U.S. southern border.
It's called the Constitution of the United States.
Legal Roadblocks
The Constitution has provisions for joining the Union in the New States Clause. That's happened plenty. But the other way around? There's nothing in the Constitution about a state leaving the Union.
But Yes California points to an 1869 Supreme Court decision that may provide them with a literal out. The case is Texas v. White — yep, those independents in Texas, of course — in which the court ruled that states could not unilaterally secede from the Union.
Yes California agrees. But they point out this passage, from the decision:
(The bold is ours.) Yes California is ruling out revolution — really, no one wants to start chucking avocados back and forth — but insists the way out is if they get the other states to go along.
What California is looking for is an amicable divorce.
Breaking Up Is Hard to Do
The people at Yes California see two routes to get that done.
In the first scenario, after a majority of Californians vote on a statewide ballot to pursue secession (and it passes), a state delegation heads to Washington and proposes an amendment to the U.S. Constitution to allow secession. According to Yes California, two-thirds of the House of Representatives and two-thirds of the Senate would have to approve. The proposed amendment then would have to be OK'd by 38 of the 50 states.
The second way skips the Washington step and, after the statewide ballot passes, calls for a convention of states, where a proposal would have to be approved by two-thirds of those delegates. If passed, Yes California says, it goes to individual states where legislatures would vote on it; again, 38 of the 50 would have to pass it.
Even if the Calexiters got that far — pretty unlikely, really — they might be faced with things they never saw coming. David Carrillo is the executive director of the California Constitution Center at University of California Berkeley School of Law. He, along with senior research fellow Stephen Duvernay, lay out the prospects of secession in a post on a blog that covers the Supreme Court of the State of California. They write:
Any way you look at it, a Calexit won't be easy. Impossible, though?
That's what they said about Donald Trump.
