Chalibi isn't done, he will be a huge player in the future. He can triangulate between the religious shia and the secular groups and be "kingmaker" on any given issue.
Chalibi is a bum - And he is simply a smoke-blower - He will wield less and less power as time moves on - Our SOF that worked with him on the ground didn't trust him a lick and those Iraqi's working with him now will trust him less and less as time goes on.
Allawi is a good man - Lets hope he stays as part of any governing body in Iraq for some time -
