Deletion of Later-no-harm criterion

Comment: These appear to be articles that have to do with the mathematics of voting, which is the subject of a good deal of interest.  I'd be inclined to refer this matter to an expert on these topics; there may be a better name for this, and it lacks context and is not clearly written.  I am not convinced yet that these articles are |original research and they pass my own "smell" test
