I volunteered in Iowa in 2007 because, like you, I had friends serving in Iraq. I had friends who were looking for jobs, others who couldn't go to the doctor because they couldn't afford it. I felt that had to change. So I knocked on some doors. I registered voters. And I'm volunteering again because my friend Matt got a job at a Detroit car company that still exists, and Lauren can get the prescription she needs. I'm volunteering because Josiah is back from Iraq, Chris is finishing college on the GI Bill, and three weeks ago, my buddy Kevin's boyfriend was able to watch him graduate from Marine Corps training. That's change!
