NAFTA is not a regulation of commerce by the congress, but rather an abdication of the authority to regulate commerce to cabinet-level representatives of the NAFTA member nations. There is no such authority under the constitution for the congress to abdicate authority, except by treaty, and then by 2/3rds majority vote.
