The girl spotted an unfamiliar box containing Hanlon's dusty, banged up old firefighter's helmet. "Dada, what's that?" she asked. Hanlon's mind raced back 15 years when he and hundreds of other first responders rushed inside the World Trade Center after terrorists flew hijacked airliners into the North and South Towers. "Oh, that's what Daddy used to do for a living," he explained. She tried to ask a few questions, Hanlon recalled during a recent interview for the documentary, "9/11: Fifteen Years Later."9/11 firefighters reflect on 15th anniversary and new anti-terror tactics"Everything is about fear and who to be afraid of," says firefighter who survived terror attacks

question:
(CNN) In October 2007, the Gallup polling organization wrote that, "Gallup's 2007 national presidential polling strongly points to [Hillary] Clinton winning the 2008 Democratic nomination. Barring something unusual or otherwise unexpected, she is well positioned for the 2008 Democratic primaries." Gallup was wrong. In June 2008, it wrote, "After winning one of the most competitive nomination battles in U.S. history, Barack Obama faces what looks to be an equally tough general election for the presidency." Gallup's polling had Obama and John McCain neck and neck, with McCain leading by a marginal point. In November 2008, Barack Obama was elected president, winning 52.9% of the popular vote to McCain's 45.7%.Sally Kohn: Polls that show Trump closing gap with Clinton alarm some on left, encourage Sanders and supportersNot so fast, she says.
