"Hey guys," President Obama greets supporters in a video shot last week in Iowa City for Organizing for America, his former campaign arm, right before he spoke to a crowd of well-wishers.
“The reason we were able to do this is because of you,” he says of the health care reform victory.
“You were knocking on doors, you were making phone calls,” he says, expressing gratitude for their grassroots efforts. “It shows you can make a difference the same way you made a difference during the campaign,” the president says.
"Thank you so much. Alright, now I've got to go fire up the crowd."
