Obama tells Couric about his 'stupid mistake,' and what a win would mean

Katie Couric has just posted her final interview with candidate Sen. Barack Obama on YouTube, and it has  some good moments.  Obama tells Couric that his line about small towners becoming bitter and clinging to guns was a "stupid mistake on my part," and that it became "Exhibit A of Democrats saying something that made people feel like they were being insulted." (That's at 6:09 in the below clip.)

Couric also asks Obama about what it will mean to him personally if he gets elected. (8:26)

He describes a litany of people coming up to him on the campaign trail, telling him stories of hardship, including from older people of color. "But it's not just a sense of the history made because of race.  There is also this overwhelming feeling of humility and gratitude where you say, 'Boy, I really better come through for folks if I win this thing, because they really need it.' "
