With the prospect of Calexit, I would definitely consider having California join Canada. Preexisting trade deals, membership in NATO and NAFTA, and a country used to bilingual culture would all be a great fit for us.
Calexit will of course never happen. Any secession attempt would automatically lead to yet another civil war. California would be crushed.
In all seriousness, Trump becoming president shakes my belief in reality. It certainly has made me see that anything truly is possible.
The explaination that the universe is an elaborate simulation seems not just plausible, but really like the most likely explaination.
What seems impossible today is just another run of the mill fact of life tomorrow.
