I think the US is precarious enough that the loss of CA would make the US economy unrecoverable. I think the East Coast would also immediately secede, since without CA the country is in a state of permanent Republican rule. Chicago and Detroit would probably petition to join Canada. I think loss of California would be a blow the US could not recover from as a nation.
More like 15% of GDP hah
