U.S. Secretary of Agriculture Tom Vilsack won't say if he wants to be considered as a vice presidential candidate but has some clear ideas about what he thinks presidential candidates ought to be talking about.

Vilsack, in a wide-ranging discussion with the Free Press, said he is hoping that presidential candidates talk about climate change and the controversies about genetically modified food during presidential debates and campaigns.

Vilsack, 64, argues that politicians and interest groups from both right-wing and left-wing are taking political positions that are dangerous for the country. He also said his mission is to prompt presidential candidates to talk about both issues."As we enter a presidential campaign...I hope that there is a conversation about science in this debate," Vilsack said. "I hope there is a real meaningful opportunity to educate Americans about the important role that science needs to play and whether or not we will continue this war on science on both the right and on the left of the political spectrum."
