Hayden Panettiere

When I turned 18, was the first time that I really started concentrating on politics. And I started doing so because I realized that in order to really create and generate change, it has to come from changing laws... so I started campaigning for Norman Lear's foundation, which was Declare Yourself.

At one point, my house was a school for autistic children. I opened up my doors to about 30 kids and their families at the time. I was turning into Mary Poppins because I had to do something for these kids who have nowhere to go. So my house was the school for two years.
