When canvassing the public about who they admire most, Gallup asks an open-ended question: "What man that you have heard or read about, living today in any part of the world, do you admire most?"
Typically, most people name the sitting president, then the rest of the responses are all over the map. Mandela has been in the low single digits, but that has been enough to consistently put him among the top 10 most admired men. And in 2012, he was ranked second behind President Obama.
