I'm curious what has turned the Japanese press against Bush. When I was there during the 2000 election the public was overwhelming in favor of Bush over Gore.
At any rate, to answer your question, the press just told the great masses of Japanese, over and over again, what to think about George Bush. Very little independent thinking there. The populace is extremely exploitable. It is even worse in S. Korea, if the press there paints someone as "evil" and that we should all hate them.
