To answer the question, I think if the right wing gains enough control of the media, and gets to reinvent history as it is able to be reinvented later when people are ignorant, they could convince a lot of people of another message, the George Bush who made 'hard choices' and was the leader who responded to the events of 9/11.
He already has about 25% of the nation who thinks he's wonderful, despite the evidence, amazingly.
Our larger problem is that the approximately 50% of American voters who voted for him in two elections are ready to be fooled again by the next republican.
They don't understand why Bush is a bad president, for the most part. They're still fooled by the republican propaganda; the don't understand the issues of wealth, corporatism, etc.
We desperately need for the public to become more educated, and that's not happening, the opposite is among the right.
That's why Talk Radio is so key for them - it fills all the hours they can spend on politics, less chance of any 'liberal' information getting through.
