I think Brit is outraged like us here. On Fox roundtable couple of days ago, everyone agreed with that view and Nina Easton came close to saying she could not believe how Armitage is digesting his food or something of that sort.
Powell's and Armitage's continuing silence I see as being like ostriches w/their heads in the sand, letting their Hate Bush media allies keep saying "Nevermind", "Old news", and/or "Let's move on" enough times that they'll be able to uncover their heads and keep on being the liberal darlings.
