How does that invalidate the idea that Bush, or any of the current crop of presidential candidates, would set up a fascist state?
Go read Naomi wolfs book The End of America. It's happening before your eyes. When you search vehicles without cause and demand your id at checkpoints all the time. When they arrest you for filming the police, destroy your camera, and then let you go, you're living in fascism.
You think that America, which prizes freedom above everything else, is going to just turn fascist over night? You think the American people would go along with that?
If you condition the people through incremental change, through the media, and several generations of citizens, then it makes the process that much easier, even if it takes longer.
Don't worry, there is going to be an even either this year or next where the current president, or the next will implement martial law and it won't end. Corporate fascism is already the defacto policy of the US government. Full blown facist police state isn't far off.
