Are Bush supporters just plain ignorant, or are they living in a state of denial?

As a European, I am tempted to claim that Bush supporters are mainly just ordinary Americans, ignorant - or should we say uninterested to find out - of not only of the world outside the borders of US, but also of what kind of people rule their own country. Add a bunch of Bible Belt loonies who live even more hermetic lives and you get this kind of numbers. A poll that I shaw in spring claimed that 59% of the people who voted Bush in the 2000 elections claimed that they don´t follow news at all, not from TV, not from newspapers, not from radio, not from the web.
