Oh hey did y'all know that with the US population of 327 million you'd only need 11.5 million well organized people to successfully topple a tyrannical regime?
Historically, any movement that was able to mobilize that amount of people never failed. Did y'all know at this level of organization the military would have a hard time suppressing the uprising since statistically this amount would include their friends, family, neighbors, and coworkers. It'd sure be wild hahaha wow cool fact
Anyways here's how Bernie could still win..
china was weird. the kuomintang had a left wing faction that got purged under chiang-kai shek. the left's leader, wang jingwei, joined the invading japanese in response to the purge, and the proponents of the left basically joined the communist party after that shitshow that happened. the communists directly seized power in the northern foothills and mountains and made a pact with the devil (chiang kai shek) to fight off the japanese. so they didnt necessarily have dual power, but direct control of various rural regions. they did nominally join the KMT's army, so I guess you could argue that was a form of dual power.
the communists began to really seize power after the japanese retreated and the USA wasn't able to parachute enough KMT garrisons in to cover their retreat. manchuria was a power vacuum that fell immediately to communist chinese, supported by the soviet union tentatively.
Taiwan and the mainland still both revere Sun Yat-sen, which is an amusing thing.
