Question the timing. Expose the inaccuracy. Throw in references to Jayson Blair. Make comparisons to Dan Rather. Most of all, expose Kerry as the kneejerk alarmist he's become, someone who undoubtedly gets an extra spring in his step whenever bad news or allegedly bad news comes out of Iraq.
I believe Bush must defend the troops (his troops).
He can't let it stand anymore than he let stand the Tora Bora (bin Laden) business.
