AOC et al old style Purritsn with speculative theories.

 Like any Marxist, AOC, the Squad, Sanders et al

there lies in their cupboard, old style Puritanism

in their Weltanschauung (a particular philosophy or view of life; the world view of an individual or group) such people are free wheeling speculatives, and driven as they are, speculate on the lives of others i.e US citizens.
