Trying to attack McKinney via Obama with exaggerated distortions is, in some ways, a very good sign -- they are that concerned about her candidacy.
It appears that they need to turn people away from her before anyone can hear what she has to say, especially potential Obama voters. There will be more to come, but we need to respond.
Marc Cooper is a writer for the Nation, a publication that does their best to trash anyone who asks too many questions and defend most official version of events, no matter how transparently. For example the Nation published an attack article on The New Pearl Harbor, by David Ray Griffin, authored by CIA agent, Robert Baer, that started with the line: "Conspiracy theories are hard to kill," and went downhill from there. This is what the Nation and it's writers are about -- defending the official version of events and working hard to take down anyone who asks too many questions through distortion, smears and innuendo.
