Delegation vs. representation: what about Engels?

[Die Neue Zeit]

"However, the question of the republic could possibly be passed by. What, however, in my opinion should and could be included is the demand for the concentration of all political power in the hands of the people’s representatives. That would suffice for the time being if it is impossible to go any further." (Engels)

Practically none of the discussions regarding "delegative democracy," even those firmly on the left, quote Engels for the purpose of rebutting his argument re. "people's representatives" (or, in today's language, workers' class representatives, and that's before going into subjects like statistical representation (http://www.revleft.com/vb/delegation-vs-representationi-t142506/index.html?p=1880553)). What's right or wrong with the formulation Engels provided in his critique of the first draft of what would become the Erfurt Program?

[Vladimir Innit Lenin]

Technically, any delegate is workers' class representative. Representation becomes delegation, somewhat, when the representative is bound to a specific program of policy enaction/voting (via a vote of their constituents) and subject to democratic recall.

I don't think actual, pure delegation, in terms of having to delegate on every single policy, vote or action, is really viable on anything higher than a parish, district or city-wide scale, but the idea of quasi-delegation is certainly interesting, and probably has entered the left-wing lexicon as to what we think of as 'delegation'.
