John Harwood from the Wall Street Journal and General Barry McCaffery on Meet the Press have both just talked about needing "new civilian leadership in the Pentagon." Lieberman reminded us of his call for Rumsfeld's resignation on Face the Nation. McCain reiterated his lack of faith in Rumsfeld on Meet the Press as well.
As I've said, Rumsfeld will have to go before the midterms. Loyalty is important, and all, but keeping their congressional majorities trumps loyalty handily.
