Glenn Greenwald is living proof of the meritocracy of journalism on the Internet. The best commentators and writers rise to the top based on reader response. Internet scribes are not guaranteed a sinecure of mediocrity, such as David Broder and Robert Novak are in the mainstream media. Greenwald earned his now national reputation and Salon.com writing position by having something to offer: trenchant, credible analysis.

Greenwald started as one blogger among hundreds of thousands with his site "Unclaimed Territory." As a Constitutional lawyer, he quickly became a "go-to" commentator on the nuances of Bush Administration assaults on the Constitution like the outing of Valerie Plame and illegal wiretapping. Greenwald penned a book, "How Would a Patriot Act? Defending American Values From a President Run Amok," that received rave reviews and became a progressive bestseller.

Despite his broad appeal to BuzzFlash readers and other progressives, Greenwald is not a rabid partisan. He wields the scalpel of a keen legal mind that is frustrated with the blatant disregard of the Bush Administration for the rule of law and America's most fundamental legal foundations. In short, he in some ways is a true conservative in that he passionately believes that the Constitution should be respected, not abused.

In fact, Greenwald reminds us of the paradox that the radical right claims to be strict Constitutionalists when they are, in fact, ardent Constitutional revisionists. Greenwald respects the Constitution and the body of law that has accumulated over the past 240 years. The Bush Administration does not.

His second book, "A Tragic Legacy: How a Good vs. Evil Mentality Destroyed the Bush Presidency," should be another bestseller when it comes out on June 26.
