I was listening to Bill Kristol on FNS yesterday. He said after the election, Rummy will go. Brit basically scoffed at him and said that's what you said in the last election.
Kristol is also anti-Rummy (just like McCain) and never has a kind word for this administration until he has no choice but to support it.
As far as people on the ground, I will defer to those who are there, but I believe if commanders on the ground were in disagreement we would be hearing more about it.
