So is this blog post getting around on the Internet? It's kind of worrying that it's not getting that much attention here.
It was duly trotted out on every talk show, talking head show and political hack show on TV and radio. It got no traction, ie. did no damage, therefore nobody really cares to discredit it.
Since Rathergate, most people are leary of these sort of "bombshell" memos. They know they're fake.
The word on this story is not out on full throttle on FR.
