As noted on the NRO, The Corner, these are all Republicans, not conservatives, and have all been opposed to the war on terror on all levels. Bob Barr works for the ACLU, for Pete's sake.
Let's see some specifics (aside from Barr; we all know about him). Have any of them come out against the war in Iraq, for example? I'd have to doubt that David Keene could be opposed to the WOT "at all levels" and still write for FrontPageMag.com. So pardon me if this NRO canard sounds just a little bit on the tinfoilish side.
