No, it did not. Wilson was sent to Niger in February 2002. Yes, I've seen your theory before, but the dems aided a plot, it was NOT a Kerry Kamp plot (they weren't that bright or resourceful).
Well, Wilson, himself was the source of the dates that he met with the Kerry campaign head and the story followed that date by about a month. Since the guy was a know dirty tricks guy, it's only natural that he be blamed for the Bush exposed a CIA agent story.
