The WSJ Opinion pages generally consist of articles written by The Editorial Board and also those submitted by guest contributors. It would be hard to argue that opinion pieces written by external authors and published by the WSJ have any consistency or standard in factuality or completeness. For example, the column frequently includes content from politicians, business leaders, or former campaign managers like Karl Rove. From what I have seen, the WSJ does not edit external opinion pieces, but can write a short disclaimer.
