With a massive American flag as a backrop, US Democratic presidential candidate Senator Barack Obama (D-IL) and Senator Hillary Clinton (D-NY) face supporters as they campaign in person for the first time in the town of Unity, New Hampshire, June 27, 2008. [Agencies]"Unity is not only a beautiful place as we can see, it's a wonderful feeling, isn't it? And I know when we start here in this field in Unity, we'll end on the steps of the Capitol when Barack Obama takes the oath of office as our next president," Clinton said from a podium as Obama sat next to her on a stool, coatless with his white shirt sleeves rolled up. She wore a powder blue pantsuit; he wore a light blue tie.
