FILE - These file photos, Oct. 7, 2009, left, and Nov. 28, 2012, right, shows President Barack Obama speaking in Washington. Four years after he was the fifth-youngest president to take the oath of office, Barack Obama now is 51, his hair more gray, his face more lined. The changes aren't all physical: As he enters Term Two, he is sounding more confident, vowing a harder line on negotiations, relying more on trusted allies, promising less, expressing more cynicism about the grip of partisanship on Washington. And perhaps most important, he seems more convinced of a need to keep the public with him, coming full circle to his people-driven 2008 campaign. (AP Photo, File)
