I think, certainly, Barack Obama has created an opportunity for America to understand that diversity is a blessing, diversity is a strength. It isn't necessarily something to be concerned about. And I think, at the end of the day, we're going to learn that this country operates best when it celebrates and surrounds itself and appreciates diversity, and doesn't shun it.

People don't understand rural America. Sixteen percent of our population is rural, but 40 percent of our military is rural. I don't believe that's because of a lack of opportunity in rural America. I believe that's because if you grow up in rural America, you know you can't just keep taking from the land. You've got to give something back.

We have a long tradition in this state of caring for our neighbors - it is truly an Iowa value.

The rise of childhood obesity has placed the health of an entire generation at risk.

Food during my early years was a very difficult issue for me. I grew up in an addictive family. My mother had serious problems with alcohol and prescription drugs. I was an overweight kid.

I grew up in a city. My parents would think there was something wrong with America if they knew I was secretary of agriculture.
