premise: In the Senate we passed the right of Americans to import drugs from Canada. But the president and his friends took it out in the House, and now you don't have that right. The president blocked you from the right to have less expensive drugs from Canada.
hypothesis: Drugs are more expensive in Canada.
reason: The president blocked you from the right to have less expensive drugs from Canada, so they are less - not more - expensive. Maybe the model thinks they are more expensive because the legislation failed??
