Denver, Aug 26 : It was a family affair for the Obamas last night - Michelle delivered the keynote speech at the Democratic National Convention, Barack appeared via satellite video, and their youngest daughter, Sasha, stole the show in the end.

Barack Obama, speaking live from the campaign trail in Kansas City, joined the three.
