Regarding Scott McClellan, many folks are using the before-after technique of analysis -- what McClellan said before his book, from the White House microphone, versus what he says now.

Credit the Washington Post's Howard Kurtz with employing that same technique, but this time on someone who's embraced McClellan with his own microphone. From Kurtz's column today:

McClellan granted his first cable news interview last week to Bush-bashing MSNBC host Keith Olbermann, while Bill O'Reilly accused the ex-spokesman of initially blowing off his Fox program in favor of "far-left venues." Olbermann hailed the book, "What Happened," as "a primary document of American history" that contained "poetry." Talk about role reversal: It was Olbermann who said in 2005 that "whenever I hear Scott McClellan talking about 'media credibility,' I strain to remember who it was who admitted Jeff Gannon to the White House press room and called on him all those times." (Gannon, a conservative blogger with an X-rated past, now says, "Scott McClellan's credibility is zero.")
