Bill is not the only one to talk about a slow moving coup. But he is, to my knowledge, the first to bring it alive with a story that puts us right in the middle of a present and future dystopia.
I've seen or read all the other slow moving coup analyses. This was the first time I felt truly shaken, as if it was really happening. There's a big difference between that reaction and "slow moving coup, yeah, that's true, I get it, yada yada yada, what else is new." Telling it as a story was a brilliant idea, which worked as intended.
