Yes, the issue-position-argument (IPA) model was developed for such purposes, and similar models are widely cited in the academic literature about argumentation and computer support for same, etc. (One very useful elaboration of this is called TIPAESA, for: time, issue, position, argument, evidence, source, authority. Unfortunately, I do not know of a good reference for this model; it seems that it was only developed informally, by anonymous folks on some political wikis.) But it’s still useful to have separately managed sites for each political faction, if only so that each faction can develop highly representative descriptions of their own positions.
I would like to see one site to describe them all. To describe all those parts which can be defended rationally, with clear explanations and evidence.
