The NYT provides essentially the same analysis of the Supreme Court that the WaPo did below. The provide statistics (which they credit to ScotusBlog. ScotusBlog also weighs in on this trend as well as what they anticipate will come of the Sotomayor nomination. A non-event they are calling it.).
They highlight the tactical nature of John Roberts who they argue has positioned the court where they are now poised to make substantive changes to a variety of previous constitutional holdings.
By the way, the increasingly accepted term for this type of behavior is "minimialism."
I anticipate spending the bulk of Monday discussing these specific findings in my Monday 2302, and Tuesday 2301.
