“After four of the most challenging years in the nation’s history, his chance to leave office as a great President who was able to face crises and build a new majority coalition remains within reach.” TIME‘s last line on Obama.

TIME: To understand how he kept his job, the best place to start is where he did. In early 2011, David Simas, a former registrar of deeds in Taunton, Mass., who had become a senior White House aide, switched on what might be called one of the largest listening posts in U.S. history. For months on end, two or three nights a week, Simas and his team secretly gathered voters in rented rooms across the swing states, eight at a time, the men separated from the women. The Obamans poked at their guinea pigs’ animal spirits, asked for confessions and played word-association games. (Among swing voters, Democrat often elicited Barack Obama, and Republican would yield words like old and backward.) Live feeds of the focus groups were shown on computer screens at campaign headquarters in Chicago. The first discovery Simas made held the keys to the kingdom. “Here is the best thing,” he said of Obama when he went back to home base. “People trust him.”

In an age of lost authority, Obama had managed to maintain his. In group after group, the voters told the researchers they believed the President was honest, lived an admirable personal life and was trying to do the right thing. “Here’s what I heard for 18 months,” Simas says. “‘I trust his values. I think he walked into the worst situation of any President in 50 years. And you know what? I am disappointed that things haven’t turned around.’ But there was always that feeling of ‘I am willing to give this guy a second shot.’”

In different rooms, behind different one-way mirrors, Republicans made the same discovery.
