Changing times: Politicians' tears more common now - Article Photos 4/5

FILE This Wednesday, Nov. 28, 1990 file photo shows Margaret Thatcher making a statement to reporters as she leaves No. 10 Downing Street, Westminster on for Buckingham Palace where she will resign as Prime Minister to Queen Elizabeth II. 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. The enduring image of Margaret Thatcher's departure from office is the tearful face captured by photographers in 1990 as she left the prime minister's official residence at 10 Downing Street for the last time after 11 years as prime minister.(AP Photo/Martin Cleaver)
