Kerry's position on Iraq: consistent from the beginning

I can't speak for this myself, having not done the research, but according to Marc Sandalow of the San Francisco chronicle, Kerry's policy statements, speeches and votes on the invasion of Iraq have been consistent, albeit nuanced and middle-of-the-road. Josh Marshall provides on his website the following passages from the article:

"[A]n examination of Kerry's words in more than 200 speeches and statements, comments during candidate forums and answers to reporters' questions does not support the accusation [of flip-floping]. As foreign policy emerged as a dominant issue in the Democratic primaries and later in the general election, Kerry clung to a nuanced, middle-of-the road -- yet largely consistent -- approach to Iraq ...

"[T]aken as a whole, Kerry has offered the same message ever since talk of attacking Iraq became a national conversation more than two years ago."
