Changing times: Politicians' tears more common now

FILE This Monday, Nov. 5, 2012 file photo shows tears running down the cheek of President Barack Obama as he speaks at his final campaign stop on the evening before the 2012 election, in the downtown Des Moines, Iowa. It seems a strange sight: The president of the United States, sometimes called the most powerful person in the world, breaking down in tears thanking campaign workers for their tireless _ and ultimately successful _ work on his behalf. But Barack Obama isn't the only world leader unashamed or unable to avoid being seen crying in public. (AP Photo/Carolyn Kaster)
