Romney played it safe in the third, foreign policy debate. This tells you his team believes he is ahead.
Obama acted like a challenger, like a guy who is behind. Which is probably what his team believes, though they won't say so. Romney won by not losing, Obama lost by not winning.
Many conservatives wish Romney had landed some serious blows concerning Benghazi and bowing and other things. This wasn't the time or place to do that. Neither side talked about drones which both plan to continue to use.
Romney correctly kept his eye on the prize, on what he needed to do to get elected. In other words, not worry the voters about foreign military adventurism.
