Well, okay, not quite. It seems obvious that bin Laden does not want to see George W. Bush elected to a second term, but if the president has handled the War on Terror as incompetently as the Al-Qaeda chief suggests, then wouldnt he want a Bush reelection more than anything else? On the other hand, if he wanted to use reverse psychology--he really wants Bush to win, so is making it appear that he prefers Kerry--I find it hard to believe that he would be playing up the presidents alleged incompetence.
No matter how one looks at it, the really puzzling part is why he would think that such a message would work; perhaps hes hoping to boost anti-Semitism by linking his terror campaign to U.S. support for Israel. But I cant see this as anything else but a boon for the Bush campaign.
By the way, Power Line notes the similarity between bin Ladens words and arguments heard in Fahrenheit 9/11. "Do you suppose there are any Democrats honest enough to be embarrassed that Osama bin Laden has enthusiastically adopted their campaign themes?"
