I think Calexit is similar to Bernie Sander's presidential campaign and why some progressives supported him not with the idea that he'd win, but so to give progressive policies and ideology more recognition in national politics. Similarly, Calexit can raise issues about the electoral college, how progressive policies have benefited CA and so the country could copy our policies, how CA pays more in federal taxes than it receives, and many of the taxes go to fund states ruined by conservative policies (such as Kansas). It can also be nice for Californians as a boost in morale during the GOP control for the next few years, too.

But at the same time, Trump did win, which was supposedly impossible. At this point, we really shouldn't say Calexit is impossible because the impossible already happened. It's a very strange time in American politics. I don't think it'd be too shocking if two hundred years from now, some states had seceded. It's not out of the scope of how gigantic (and federal) countries/regions have changed shape throughout history, and the US is one of the few modern gigantic countries around. The US is already starting to form little microcosms so at odds with each other it is hard to believe they both belong to the same country. I believe though that CA would likely be the first state in a hypothetical secession scenario to break away because there's a multi-generational resentment toward how California has the 6th largest GDP etc etc but gets ignored a lot. People abroad share this view to, that California is a very different state. When you compare Calexit to Texas's secession campaigns, after you take away problematic things like water and the US army, California really could be its own country. If there's fiascos similar to AP calling Hillary before CA voted in the primary during Trump's administration while there's also a Calexit movement, I would not be surprised if it gained traction--not that Calexit would happen, but that it'd gain traction. It'd remind me of how the cultural revolution in Mexico brought people together, except for California it would be about how we have more in common with Sweden than the US politically speaking (except for weed), so there's a bit of Californian nationalism cultivated.
