I’m not sure how making the Louisiana Purchase is at odds with limited government.
Jefferson negotiated that deal without congressional input. It was probably unconstitutional the final agreement with France. But there was no one going to file a complaint about the greatest real estate deal in history.
It suggests an implied power, which Jefferson didn’t believe in very much. He actually proposed a Constitutional amendment to accommodate it. Jefferson’s Cabinet members argued that the Constitutional amendment he proposed was not necessary. He reluctantly [so the story goes] acceded to their arguments.
Lol!
