Should the Senate vote for Obama’s Trans-Pacific trade deal?

President Obama has been pushing a bill to give himself the authority to make quick decisions on trade deals. This would fast track the finalizing of the Trans-Pacific Partnership - a major free-trade agreement with Mexico, Japan, Singapore and seven other nations. The U.S. Senate failed to pass the bill with opposition coming from Democrats. Many cite the large amount of authority that would be given to Obama and the impact of the trade deal on middle-class jobs as reasons for not supporting the bill. Do you think that the Senate should support this trade deal?
