China may be behind it, but they need and have a C2 structure in this country and on the ground. And they have cover which hides their involvement and provides them with plausible deniability.
China’s also been running a huge voter registration drive. There is no ‘may’. There is no doubt that they have the Methods, Means, Motive, and Money - as well as experience overthrowing governments. Someone is throwing many billions of dollars into overthrowing the USA, and it ain’t Soros.
