A union-sponsored ad charges that Arkansas Sen. Blanche Lincoln’s support of "unfair" trade deals "made it impossible for American workers to compete." But several economic studies say trade deals, like the North American Free Trade Agreement, have had a small impact, or even a positive one, on American jobs.
As we said last week, this ad starts with a true claim about union workers at a Cooper Tire plant making wage concessions to ward off a threatened closure.
