There are a couple of good articles on Salon (and also at True Blue Liberal) that I don’t have time to comment on, but they’re good reads. I’ll give both links for each article.
Update: See also “Another General Calls For Rumsfeldâ€™s Resignation” at Think Progress. This is genuinely extraordinary, for reasons modus potus explains here. But I have it on good authority that the brass has hated Rummy from the get-go.
