Blood. It's nature's lube
I was reading about this a few weeks ago after the election when it was gaining steam on social media since I live in California and was interested in learning about the legality and consequences of seceding.
The first thing to consider is that it's essentially impossible for a state to secede, it just isn't going to happen. Even if the measure gets put on the ballot in the future and Californians were to vote in favor of it, all other states would have to give their consent for a state to leave, and that's where this would essentially become an impossibility. California is such a huge state, and pays so much in federal taxes because of the massive population that other smaller states really depend on that federal money that comes from California. They would definitely not be in favor of California leaving.
There's also the issue with the drought that is going on here, we get a good portion of our water from the runoff from the Colorado river, that would become complicated if we left the union. There's of course also the issue with military bases and the like. I also believe we'd have to pay our share of the national debt before the state was allowed to leave. So there are issues with the prospect that would need to be ironed out, and they are significant issues.
However, if those things were to be solved, then California would be in a pretty unique place as definitely being able to survive on our own. We have the 6th largest economy in the world, a thriving tech empire up north, and a population of about 40 million people. We'd be able to survive just fine on our own, though there would obviously be difficult decisions such as how to handle immigration. It would also be interesting if other western states were to join us. There was also talk of Washington and Oregon seceding as well. And then the three states could create a new nation together. Canada also said that if those three states were to secede, then we'd be welcome to join them.
Anyways, in short - it's interesting to think about, but ultimately such a vote would be little more than symbolic, the rest of the nation would suffer quite a bit if a state as large as California left and wouldn't let it happen, and California itself would have to deal with pretty significant issues. Won't happen.
It's also worth noting that the idea of secession wasn't created just a few weeks ago when Trump won, there has been a group pushing for it for a couple years now.
