Former Democratic Senator John Edwards has found himself in the center of the debate over factory farming. When Edwards first ran for the U.S. Senate in 1998, he defeated Republican incumbent Lauch Faircloth, who had been a large-scale, commercial hog farmer and operated in the second-largest hog-producing state. Now, Edwards is spending much of his time in the number one hog-producing state, Iowa, and is running on a platform of protecting small farmers and rural communities from the environmental pollution and economic devastation caused by agribusiness.
