The Center for American Progress has a contest going on: Find a single reference by Bush or top WH official to Al Qaeda or Bin Laden before 9/11, and you'll receive a prize. After all, if Clarke is a kook and Bush was on top of AQ terrorism from Day One, surely he wouldn't have been shy about it.
For fun, I quickly googled for a statement on Iraq by Bush pre-9/11. Many on this blog probably already know this, but on Feb 16, 2001 -- 4 weeks into office -- Bush had already started bombing Iraq as part of a "strategy."
This contest could be fun.
