Hillary Clinton thanked Karl Rove on Fox and Friends this morning. The context was benign, but the "Thank You" coupled with the split-screen of Clinton and Rove should be cut into an Obama ad regarding Hillary's tactics in this campaign.

I imagine Obama will tie the foreign policies of Bush-McCain and Clinton together in his next round of advertisements, especially since she voted for the Iraq war, voted for the Iran resolution and has co-opted the "antagonize our friends and enemies" foreign policy of the Bush Administration.
In fact, this should be spliced together with Clinton's speech on the floor of the Senate during the Iraq war vote in which she said that she knew this was a vote that essentially authorized military action and war.
