Is Obama really against NAFTA? Or only when he thinks it will make him popular?

In his 2004 Senate campaign, Obama said the US should pursue more deals such as NAFTA, and argued more broadly that his opponent's call for tariffs would spark a trade war. AP reported then that the Illinois senator had spoken of enormous benefits having accrued to his state from NAFTA, while adding that he also called for more aggressive trade protections for US workers.”Putting aside campaign rhetoric, when actually given an opportunity to protect workers from unfair trade agreements, Obama cast the deciding vote against an amendment to a September 2005 Commerce Appropriations Bill, proposed by North Dakota Senator Byron Dorgan, that would have prohibited US trade negotiators from weakening US laws that provide safeguards from unfair foreign trade practices.
