As far as I'm aware, we are understanding it in the same meaning. Winning an election is "by consensus." The most people agreed, so that is what we will do and we all agree (so it is said, even if we don't) to accept the policies promoted by the winner because "we agreed by consensus."

"Consensus of opinion" is exactly the point of "Manufactured Consent" as discussed by Noam Chomsky and explained in that video link. "Consensus", and thus "consent for policy" manufactured by those in charge or their opposition powerful enough to be a factor.

I do not deny being worthy of the title, "extremist within the US." But I'm not clear how that impacts the meaning of "consensus" or how my view affects its usage in this context.
