I suppose the left sees treaties as having the force of constitutional amendments. Has a court ever declared a treaty unconstitutional?
Any Leftist who thinks a treaty could override the Constitution should be asked “Would you think that way about a treaty with the Vatican which banned abortion?”
No treaty can override the Constitution period.
As per the article, SCOTUS has ruled in the past that no treaty may usurp the laws and protections on the books in the US. That’s not stopped people like Obama in the past though.
