The family was ushered inside ahead of a line of their Hyde Park neighbors that wrapped around the block. Fellow voters inside watched in silence and snapped cell-phone pictures, then cheered when he held up his validation slip with a smile and said, "I voted."
But Obama's campaign for president is not quite. After he voted he headed to Indianapolis for one more campaign stop in one more battleground state that Obama's trying to flip from red to blue.
"Why not? He's going to work until the last possible second," said Valerie Jarrett, Obama Friend & Advisor.
The Obama campaign has one of the largest and most sophisticated get-out-the vote operations in political history -- mixing high-tech record-keeping with old-fashioned shoe leather.
Campaign manager David Plouffe is cautiously optimistic on Good Morning America today that 270 electoral votes are well within their reach.
"We have competed in a lot of battle ground states all around the country. We have got an opportunity, we think, to get the 270 electoral by any different combination of states," said David Plouffe, Obama Campaign Manager.
"If we do what we have set out to do, there is no way they can outwork us on the ground. Our volunteers are all over this country. They have been working for weeks now," said Jarrett.
While Obama was in Indianapolis he stopped at a UAW Headquarters where he made calls to possible voters urging them to get out to the polls.
This afternoon, Obama will head back to Chicago to get ready for tonight's election rally at Grant Park.
