Politically, AQ doesn't need to waste scarce and critical terrorist teams to strike against the Bush Admin. They already have their desired results, and another attack against the US would just solidify American opinion against them.

The next President may withdraw from the Middle East or shift the fight into the intelligence, SOF and law enforcement arena. AQ would not have the luxury of fighting us in the ME, and the US would save hundreds of billions if not trillions by withdrawing from Iraq. It would negate OBL's grand strategy overnight.
