Good point. I guess the Dems can organise their lot, the GOP theirs. But who is to organise the disaffected? Herding cats methinks.
Sorry if I sound like an armchair general but when the only defence you have against tyranny is your constitution, albeit with a dodgy SCOTUS, then defence is the least worst if difficult option. Attack without overwhelming superiority is brave (aka foolhardy).
Remember if the US goes then so does liberal democracy in europe and elsewhere. Learning Mandarin may become not an option.
Oh, and the final triumph of Chinese state capitalism which is, arguably even worse than our version.
