2 alternate campaign ad ideas called "central front":

1. "Who convinced John McCain that Iraq, and not the Afghanistan-Pakistan border, is the central front in the war against terrorism?"
[clips of terrorism experts like Richard Clarke saying Afghanistan-Pakistan is where the terrorists who attacked and are planning and capable of another attack are hiding out etc; clips of McCain asserting that bin Laden himself thinks Iraq is the central front]
"How much weight will Osama bin Laden's words carry over US counter-terrorism policy if John McCain is elected President?"

or

2. [animated depiction of US troops surrounding bin Laden's cave in Afghanistan, bin Laden and his deputies nervously silent and praying inside, then a sudden pullback of troops (think the scene of orcs pulling out of Mordor to meet Aragorn outside the black gates) as Bush announces invasion of Iraq, bin Laden peeking his head out of the cave to see no sign of US forces, rejoicing]
"John McCain cites Osama bin Laden's assertion that Iraq is the central front in the war against terrorism as proof that US forces must stay in Iraq indefinitely.  Is bin Laden really the best person to make that determination for us?"
