It should be obvious from the work who the Woodward of Now is. And if it isn't Greg Sargent can explain things to you over at the American Prospect.
The guy's name is Murray Waas; he's an independent journalist who recently went to work as a staff writer for National Journal and the Atlantic Media Company, which owns the Atlantic Monthly, the Journal, and other titles. Murray Waas has been in the game since he was 18, when he started working for the columnist Jack Anderson.
By Woodward Now I mean that Murray Waas is the reporter who is actually doing what Woodward has a reputation for doing: finding, tracking, breaking into reportable parts--and then publishing--the biggest story in town. He's also putting those parts together for us.
