I believe that's true. Allawi knows a phoney loser he doesn't need to waste time on when he sees one.
I will always remember how Kerry insulted Allawi last September when Allawi addressed a joint session of Congress. Kerry went on the campaign trail instead of spending a few hours in DC, then Kerry set up a little (tiny) presser where he said some very derogatory things about Iraq and our situation, etc.
I am glad to hear that Allawi has the presence to refuse to give Kerry the time of day.
