Syndicated columnist George Will--who is, broadly speaking, a conservative; but who does not march in lockstep with any group--has recently characterized President Obama's imperial (and imperious) "offenses against the separation of powers" as "egregious in quantity and qualitatively different" from those of his predecessors. (This dovetails rather nicely with the recent observation of left-leaning Georgetown University professor Jonathan Turley that President Obama is "the president Richard Nixon always wanted to be.")
