While the Democratic candidates for President had a serious and detailed discussion on a number of important issues last night, they didn’t mention one key issue - manufacturing. In the 90 minute debate, the word “manufacturing” was not uttered once, even though it's the largest sector of the economy of South Carolina, where the debate was held. I’m not blaming the candidates or Brian Williams for the omission. The burden falls on all of us who care about not only manufacturing, but also American workers and companies, and the economic future of this country. Next time, let’s make sure someone uses the “M” word.
