Accentuating the positive is a no-brainer in campaign ads. You expect to see candidates call out their achievements and sweep any misgivings under the rug. (What alleged sex scandal? What flip-flop? What oops thing I said in the debate? Now about my stance on tax reform...)
The new Our Destiny PAC ad for Jon Huntsman tries the opposite approach by calling out a gaping flaw in the presidential campaign. The ad ends on the question, "Why have we never heard of this guy?"
Good point. Just wish they were providing answers instead of asking the questions.
