These are the most effective ads in the U.S. presidential election that have run in the past six months, according to the scores from an Ace Metrix survey. Ace Metrix tracks the advertising effectiveness throughout the year and is now also tracking political ads. The results are based on daily surveys of more than 500 voters. Participants are asked to rate each ad on a number of factors such as whether the spot caught their attention, whether they found it credible or relevant, and their likelihood to watch it again. It then scores the ads on a 950-point scale based on all those answers.
