NAFTA has long been a political objective. In 2008, then-Presidential candidate Barack Obama responded to widespread trade skepticism within the Democratic base by promising to renegotiate NAFTA to incorporate stricter labor and environmental standards. The Obama administration tried to address NAFTA issues during the Trans-Pacific Partnership negotiations, a massive trade agreement with 11 other countries, including Canada and Mexico. The TPP was deeply unpopular – Hillary Clinton ultimately opposed the deal during her 2016 presidential bid – and President Trump withdrew the United States from the TPP in one of his first official acts. After Donald Trump`s presidential election, a number of trade experts said that exiting NAFTA, as Proposed by Trump, would have a number of unintended consequences for the United States, including limited access to the largest U.S. export markets, reduced economic growth and higher prices for gasoline, cars, fruits and vegetables.  The textile, agriculture and automotive sectors would be most affected.   Clinton signed it on December 8, 1993. The agreement came into force on 1 January 1994.   At the signing ceremony, Clinton paid tribute to four people for their efforts to reach the historic trade agreement: Vice President Al Gore, Council of Economic Advisers Chair Laura Tyson, National Economic Council Director Robert Rubin and Republican Congressman David Dreier.  Clinton also said, “NAFTA means jobs.
U.S. jobs and well-paying American jobs. If I didn`t believe it, I wouldn`t support this agreement.  NAFTA replaced the old Canada-U.S. free trade agreement. In its May 24, 2017 report, the Congressional Research Service (CRS) wrote that the economic impact of NAFTA on the U.S. economy was modest. In a 2015 report, the Congressional Research Service summarized several studies as follows: “In reality, NAFTA did not cause the huge job losses that critics feared, nor the significant economic benefits predicted by supporters. The overall net effect of NAFTA on the U.S. economy appears to have been relatively small, not least because trade with Canada and Mexico accounts for a small percentage of U.S. GDP.
However, there have been adjustment costs for workers and businesses as the three countries have prepared for more open trade and investment between their economies. :2 Agriculture, in particular, has seen a boost. Canada is the largest importer of U.S. agricultural products, and Canadian agricultural trade with the United States has more than tripled since 1994, as has Canada`s overall agricultural exports to NAFTA partners.
