Reviving an ad strategy not employed since July, John McCain's latest ad out Friday, "Freedom" (subscription), features images of a young McCain as a soldier -- and a prisoner of war -- to assert his own patriotism and fortitude.

"I've served my country since I was 17 years old, and spent five years longing for her shores," McCain says in the ad. "I came home dedicated to a cause greater than my own." In another shift from nearly all his recent ads, McCain stays positive, though he does sneak in an implicit jab at Barack Obama's "hope" slogan: "Don't hope for a stronger America. Vote for one."
