Hi,
I just wanted to share this clip of my mom on YouTube speaking about Barack Obama. She did a lot of work campaigning for him and running as a delegate in PA. Here is the link to her clip on YouTube. I think it's quite good and well-articulated for a spur-of-the-moment take. I especially like the part when she points out that Obama appeals to the good side of people rather than bad things like fear.
