I think that has more to do with how the voting system is set up, and less to do with collective ignorance.
Collective ignorance of the US population is yet more propaganda they tell us to accept their abuse of our neighbors.
We don't have a choice at the voting booth, because of systematic elimination, and exclusion of canidates that oppose the system, and systematic corruption of any that might get through.
the USA was never a democracy, and what little bits of democracy that exist in the system only date to the early 20th century (i.e. 17th amendment).
Our constitution, declaration of independence, early government, where *not* written by men of the people, crowd sourced, or in any way shape or form made by either democratic, nor popular movements. They were written by the pre-existing state governments as existed under the crown.
Not since the civil war, has anyone, anywhere, really, had any voice in opposing the system of government, and the federalists have cemented any opposition to federalism as support for the confederacy.
