Messina ended the talk with a presentation of “Fired Up, Ready to Go,” a web video that takes viewers from the story of one supporter to the final rally of Obama’s campaign in 2008. The video hit at the inspirational core of the president’s historic victory four years ago, and a few of the staffers were moved to tears. For Team Obama, watching Fired Up offered a nostalgic release, carrying them away from the corporate feel of their Chicago office tower and to the movement that captured their imaginations in 2008. It reminded them of why they were grinding away now.
