Why would you think that Al Queda would not have attaced us if Al Gore was president?    It didn't stop them from the first world trade center bombing in 1993, the two US embassies in Africa, the USS Cole, Somalia, Yemen, or the apartments in Saudi Arabia.   All of these during the Clinton/Gore administration.

I don't think terrorists will stop their mission based on who is presendent of the USA.   Given the choice, I do think Ossama is one of those "foreign leaders" who supports John Kerry.
