I think this video really speaks to Barack's charisma, and the buzzword of the US campaign right now: "change." This election is giving Americans, and many other people in many other nations, a hope they have not allowed themselves to feel in a long time. It is meaningful, and it's hard not to be a bit inspired by it. The millenium has come, and we survived, so we'd better do our best to make it better.
Just as a caveat: I still don't know if I prefer Barack over Hilary, but I think they'd both give the good thing: real, solid, steaming, fleshy change. At least I really really hope so, and for now, hope is enough.
