Glenn Greenwald is probably the last neutral journalist. Respected worldwide for publishing the Snowden story, which the conservative establishment was totally against, he is completely independent of partisan politics, and is after the real story.
Glenn Greenwald is a hack. He stumbled into his one big scoop (Snowden) and since then has not really distinguished himself or shown that one case to be anything more than a lucky break. He is not independent of partisan politics, he is simply partisan on an anti-establishment axis.
