congress could set foreign trade, standards for interstate travel, what happened instead?

Brief Explanations:

The question pertains to U.S. legislative actions and what actually occurred instead of Congress setting certain standards. In practice, various factors like political - power dynamics, court decisions, and executive actions can influence whether Congress's potential actions are realized. In the context of foreign trade and interstate travel, other branches of government and real - world events often shape the outcomes. For example, the executive branch may negotiate trade deals that affect foreign trade instead of Congress solely setting the standards, and state regulations and court rulings can impact interstate travel standards.

Answer:

Instead of Congress solely setting foreign trade and interstate travel standards, a combination of executive actions, court decisions, and state - level regulations often determine the actual standards and practices in these areas.
