NUNN: Some people ask me why, with all the dysfunction in Washington, I'm running for Senate. In the end, I think it comes down to being an optimist. While leading President Bush's Points of Light Foundation, we grew into the world's largest organization dedicated to volunteer service. I've seen the power of individuals to work with businesses, charitable and religious organizations to make change. I know things can be better. I'm Michelle Nunn. I'm optimistic about Georgia’s future. That's why I approve this message.
