President Bush and the Democratic Congress are locked in fierce conflict over approval of U.S. free trade agreements with Colombia, Panama and South Korea. Presumptive presidential candidates Barack Obama and John McCain hold sharply different views on the merits of free trade and globalization. Whether we’re prepared for it or not, a major national debate on these issues is looming for the fall campaign and beyond.

Meanwhile, our venerable House of Representatives, in the context of the Colombia agreement, has recklessly changed the rules for congressional action on trade legislation. By rejecting long-settled procedures that prevented congressional sidetracking of trade deals negotiated by presidents, the House has hamstrung U.S. trade policy and created the gravest threat to the global trading system in decades.
