I think he's different. Polarizing on given stories, sure, but also non-partisan.
I appreciate Greenwald's journalism because he doesn't play favorites when it comes to calling people out. People seem to think he's a liberal but over the past decade he's been just as likely to call out Obama, Krugman, et al., as Bush/Cheney & Co.
Greenwald is definitely non-partisan, and in fact he goes to great lengths to point out that the people who supported him when he reported on government abuse during the Bush administration have become some of his strongest detractors when he reports on the same things under Obama's administration. He doesn't really hide his own personal ideologies but they're certainly not loyal to any particular political party.
