Meanwhile, it's discouraging to see a serious trade debate reduced to political gamesmanship. Bad enough that Hillary Clinton, a die-hard TPP advocate when she served as secretary of state, has suddenly lost her voice on trade, but what one hears from some of the other presidential contenders is bordering on brain-dead. Former Gov. Martin O'Malley is against it, and so is Sen. Bernie Sanders. On the GOP side, former Arkansas Gov. Mike Huckabee and former Hewlett-Packard CEO Carly Fiorina have been highly critical, too. "Personally, I wouldn't trust this administration to negotiate a deal on a secondhand Subaru" is how Mr. Huckabee has framed the fast-track debate while still claiming to be in favor of free trade. Talk about making things personal.
