These articles might be relevant if attached to an appropriate sentence.  The first one shows Biden and Kennedy's attempts to characterize the unitary executive theory, and Alito's responses, so I guess it's relevant to the UE theory's impact on politics.  Somebody needs to go through the whole article and lay it out.  The UE theory was basically invented by Calebrisi and Rhodes, and they have argued that some prior actions can be interpreted in light of it.  It seems to me that a logical way to write the article would be:

1 Introduction

2 Development of the UE Theory (discussion in the legal press, citations to the theory by the DOJ and courts, etc).

3 Political Impact of the UE Theory

4 Popular Concepts of the UE Theory
