Young people and voting

I was listening to NPR on the way to pick up my daughter from daycare this evening, and there was a story on young people and what motivates them to vote.

The women who was being interviewed argued that young people are only motivated to vote if their is an issue that they care passionately about.

This might be true to a degree, but I also think there is a "pied piper" effect. In other words young people are more likely to be motivated by charisma. Not John Edwards or Mitt Romney pretty boy charisma, but real charisma. I don't know how to define it, but I know it when I see it. McCain has it, so does Obama.
