The 12-nation Trans-Pacific Partnership trade deal signed Monday is poised to become an election-year piñata as the Obama administration works to get it through Congress. Hillary Clinton, who supported the TPP when she was secretary of state, came out against it on Wednesday: “I don’t believe it’s going to meet the high bar I have set.” Sen. Bernie Sanders, her rival for the Democratic presidential nomination, issued a caustic statement: “It is time for the rest of us to stop letting multinational corporations rig the system to pad their profits at our expense.”
