Can the United States ratify the TPP in 2015? As the new year begins, President Obama will be working with or at odds with a Congress where both chambers have a Republican majority. The administration wants to move aggressively in wrapping up negotiations by July 2015 in an effort to ratify the TPP, which would establish the world’s largest free trade zone – 12 countries constituting one-third of global trade. While the Republican-led Senate appears prepared to grant the Obama Administration “fast track authority,” meaning that Congress must vote up or down on trade agreements without being able to amend such pacts, at the same time, some House Republicans may also oppose granting “fast track authority.” In addition, many Senate Democrats are opposed to the TPP and blocked the White House’s efforts last year to push for such powers amid pressure from organized labor in an election year. Whether President Obama can muster enough votes to ratify the pact remains unclear. Failure to pass the TPP in 2015 would deprive President Obama of what would be his most valuable economic achievement in the rebalancing effort to Asia. Consequently, many Asians would question the sustainability of the administration’s pivot.
