MCGRATH: One good thing about retiring from the Marines is that my kids get to see my hero a whole lot more. I'm Amy McGrath and this is my mom. She survived childhood polio to become one of the first women to graduate UK medical school. Her example pushed me to believe I can achieve anything, even though she thinks landing on aircraft carriers is a little crazy. I approve this message because I'm determined to help a fix healthcare in Congress, and now you know who inspires me to get it done.
