About the only reason I can find for this hatred is their view that the 2000 election was stolen from Al Gore and likely the 2004 election too was manipulation of the ignorant masses to beat John Kerry.
I think they hate W because he stands for everything American that they hate. To them, he represents the common man, the common America. In their elitist hubris, they see him as representing everything that is antiethical to their whole existence and reason for being.
US Ultra-Traitors Keller and Punch: "We support terrorists. Why? Because it help business.
We support the murder of thousands of Americans per hour. Why? It helped the circulation of our paper.
We encourage treason. Why? It hurts Bush and who cares about anything else.
We want to help the enemies of America. Why? It will sell more papers overseas.
Why do we encourage the murder of Americans for our paper's circulation?
Because without these things, we are nothing."
