6. Crane Brinton's famous "Anatomy of Revolution"

as I recall theorized that certain conditions were needed to carry out a revolution, namely a centralized city to attack as just about the only location of political power, bad economic conditions, general chaos where power is 'in the streets'.

We were never there. America is too large, too diverse, power too dispersed, even in the nation's capitol. The presidency is not a monolith. The states and judiciary weigh in on national power as well.

It's not clear how much power GQP state legislatures could amass. There would still be judiciary and blue states to deal with, as well as the power in Washington.
