Lowry apparently hasn't read the Krauthammer piece.
What would have been great, even though it would have likely been cut, would have been if she'd asked "Do you mean the Krauthammer Bush Doctrine of XXX, 2001, or the YYY Bush Doctrine of September 20, 2001, or..."? She shouldn't finish the list, lest she appear as a show-off, but should instead let the "or" hang. If Charlie failed to answer, she could ask what his version of the Bush Doctrine said; any awkwardness would be on Charlie's end, not hers.
Still, she did fine.
