Frank Rich explains the story lines of the Valerie Plame/Karl Rove scandal in his New York Times column:

"When you look at the early timeline of this case, rather than the latest investigatory scraps, two damning story lines emerge and both have legs. The first: for half a year White House hands made the fatal mistake of thinking they could get away with trashing the Wilsons scot-free . . . The second narrative to be unearthed in the scandal's early timeline is the motive for this reckless vindictiveness against anyone questioning the war."
