One of the many implications of yesterday’s election is that the new Congress will likely be more friendly toward trade-expanding agreements and less inclined to raise trade barriers.

Trade was not a deciding factor in the election, despite efforts by a number of incumbent Democrats to make it so. Many House and Senate contests were peppered with ads accusing an opponent of favoring trade agreements that gave away U.S. jobs to China. It was a stock line in President Obama’s stump speeches that Republicans favored tax breaks for U.S. companies that ship jobs overseas (a charge I dismantled in an op-ed last week). Yet on Election Day the trade-skeptical rhetoric and ads did not save Democratic seats.

Republicans Pat Toomey, Rob Portman, and Mark Kirk all won Senate seats in the industrial heartland yesterday (Pennsylvania, Ohio, and Illinois, respectively) and all three voted in favor of major trade agreements during their time in the U.S. House. None of them ran away from their records on trade.

The key change for trade policy will be the switch of the House to Republican control in January. Democratic House leaders were generally hostile to trade agreements during their four-year tenure, refusing to allow a vote on the Colombia trade agreement in 2008 even after President Bush submitted it to Congress while allowing a vote this fall on a bill to raise tariffs against imports from China.

In contrast, the incoming GOP House leaders, presumptive Speaker John Boehner of Ohio, Majority Leader Eric Cantor of Virginia, and Ways and Means Committee Chair David Camp of Michigan, have all voted more than two-thirds of the time for lower trade barriers, according to Cato’s trade vote data base. The trade-hostile influence of organized labor, so prominent the past four years, will be greatly diminished.

The new Congress will be more likely to consider and pass pending trade agreements with South Korea, Colombia, and Panama. The Obama administration has endorsed all three in the abstract, but has done little to actually push Congress to approve them. These three agreements offer an opportunity for the White House to work with the new Congress in a bipartisan way to promote exports and deepen ties with friendly nations.

The news is not all positive on the trade front. A more Republican-weighted Congress will probably not be much different when it comes to rewriting the farm bill in 2012. Republicans have shown themselves to be similar to Democrats in supporting subsidies and trade barriers to benefit certain farm sectors such as sugar, rice, cotton, and corn. And Republicans are far more inclined that Democrats to support the failed, 50-year-old trade and travel embargo against Cuba.
