They claim that presidents favor freer trade and will use the negotiating authority Congress delegates to them to reach agreements lowering trade barriers. Since presidents gain more support from their congressional co-partisans, less liberalization ensues under divided government. This theory rests on the premise that party is unrelated to congressional trade policy preferences beyond legislators' tendencies to support their presidential co-partisans. Yet before 1970 congressional Democrats were relatively free trading regardless of the president's party affiliation. Since then, the same has been true of Republicans.
Divided government does impede the efforts of presidents from the free-trading party to liberalize.
I conclude that divided government has no consistent effect on trade policy outcomes. Inc. All rights reserved.
