The Vicky for Veterans Tour stopped by the VFW post in Marshfield Friday.
One Army veteran says the big issue on his mind is the Affordable Care Act.
He says he hopes Hartzler would support its repeal.
"The insurance is so vague," says Bob Revland, a U.S. Army Veteran. "Whenever you have something that is so ambiguous that you don't know what is going to happen, that would be a major concern, I'd think to any elderly citizen or veteran."
Hartzler is set to take on Democrat Teresa Hensley.
