For all the complex issues raised at Fridayâ??s workshop on competition in the dairy industry, the question at the heart of it was a simple one: What is happening? Thatâ??s how U.S. Sen. Russ Feingold, D-Wis., broke it down to a crowd of about 600 at Union Theater on the UW-Madison campus. The event drew farmers, producers, lobbyists, politicians and economists to discuss a dairy industry that has seen rising production costs and massive milk price fluctuations in recent years.
