What are the key differences between trade liberalizers, believers in fair trade, and trade skeptics?

What will be an ideal response?

Trade liberalizers believe in lowering trade barriers both in the United States and abroad and favor open markets. The biggest proponents tend to be Republicans and members of the business community. In contrast, many Democrats are proponents of the fair trade view who believe that poor labor, human rights conditions, and environmental conditions in foreign countries make open markets unfair to the United States. Fair traders believe that trade agreements should include provisions outlining minimum standards in these areas. Finally, trade skeptics argue that trade agreements undermine U.S. sovereignty and largely benefit multinational corporations over small businesses, farmers, and workers. The most common supporters of this view are labor union allies and Tea Partiers.
