Osama is a man of change, yet he seeks to preserve family, tradition, and
religious values. He wants to stop the collapse of society, putting the
individual into context. He visions setting the family forth as the basis
of society. He seeks to put the legal system where it belongs: in local
communities. And he wants to abolish the Federal Reserve and re-create the
gold standard.

Is this a joke or to make a statement of comparison?

I consider Obama, whom I believe this satirizes, to be the least of the three evils...yet I still think the site is pretty clever.

I also don't think it really is likely to turn a single person against him, since the kind of rube really willing to accept the association has surely been in the McCain/Bush camp for years.

I'd hope that people could appreciate satire and/or humor targetting their own guy exactly as much as targeting someone they hate.
