MCSALLY: I'm Martha McSally. I was a colonel in the Air Force. I led men and women in combat. Now, I'm ready to lead. To create jobs. To protect the A-10 in Davis-Monthan. To improve education for our children. I'm determined, ready to fight, for our community, for Southern Arizona, for us. I'm Martha McSally, and I approve this message because together we can make a difference.
