(VOVworld) - Republican Donald Trump and Democrat Bernie Sanders's notable victories in the New Hampshire primary on Tuesday have complicated the path for US Congress to approve the controversial Trans-Pacific Partnership (TPP) deal this year, with a booming anti-trade fervor haunting the 2016 presidential campaign. Having long been regarded as outsider candidates in both parties, Trump and Sanders each are railing against the Pacific trade deal between the United States and 11 other Asia-Pacific countries, a top legislative priority for the Obama administration this year, in their presidential primaries. Former Secretary of State Hillary Clinton, Sander's rival for the Democratic presidential nomination, also reiterated last week that she would not support the TPP in its current form and would seek changes to the pact if elected. Major influential U.S. business groups, including the US Chamber of Commerce, the National Manufacturers Association and the Business Roundtable, have expressed their disappointment over provisions governing tobacco, pharmaceuticals and financial institutions in the deal.
