Food prices keep rising. Ag business seems to grow larger every day. Where does the farmer fit into this puzzle?   In this episode, Donna and Lonna talk to Aaron Lehman, Iowa farmer and president of the Iowa Farmers Union. They talk about the Farm Bill, the price of groceries, the politics of food policy and the farmer's voice at the table.   We find out that 'politics is the way we allocate resources'. Perhaps now is a good time to define a better vision for agriculture.
