According to Keith Olbermann:
"If the Iraq debate seems especially exhausting, it may be due to the steady erosion of the foundation for any productive debate, facts. Our fourth story on the COUNTDOWN tonight, the persistent lie a link, a preexisting link, between Iraq and al Qaeda. President Bush last week told CBS News, quote, "One of the hardest parts of my job is to connect Iraq to the war on terror." Of course, any good boss knows how to delegate the hard stuff. And so the past several days have seen a veritable assault by his staff on what, in any other plane of existence, would constitute consensus reality, the knowledge, known to the intelligence agencies of the U.S., Britain, and Israel, to the 9/11 Commission, to, most recently, the bipartisan Senate Intelligence Committee, and to many of your sharper domesticated farm animals, that al Qaeda and Iraq were not partners, allies, or even friends."
That explains it. There must not be very many of those "sharper domesticated farm animals" wandering the US countryside. As a matter of fact, I see what looks like crowds of Bush supporters standing in fields waiting to be called to the barn for milking near my home every day.
