Jefferson had little impact on the Constitution
Really? Because he was sending Madison letters advising him what to include throughout the convention. Many of Jefferson's ideas were directly incorporated into the document by Madison.

Furthermore, your claim that Madison was following Hamilton instead is contradicted by Hamilton's own activities at the convention, the thrust of which consisted of a widely ridiculed and dismissed pitch for a de facto monarchy followed by a couple of months of sitting there as New York's lone impotent delegate after Yates and Lansing left. Hamilton definitely became an advocate of the Constitution that was adopted, but its design was very different from the one he himself wanted and much closer to that put forth by the Virginia Plan.
The Va. and KY. Resolutions would mean there was no law of the land.
As opposed to the alternative in which newspaper publishers were being rounded up and jailed en masse for writing unfavorable opinions about John Adams. Some "rule of law" that is!
He didn’t even believe the Constitution allowed the Louisiana Purchase.
Jefferson was probably wrong about that. The Louisiana Purchase was done by a senate ratified treaty, so it's constitutionality is of little doubt.
Jefferson’s comments sank without a trace as far as I can tell. It took months to cross the Atlantic and there could have been very few letters to even make it to Madison in Philadelphia.
I did not say Madison was “following” Hamilton quite the contrary since at the time M was more Hamiltonian than Hamilton. He even propose getting rid of states entirely.
Your description of Hamilton’s contribution is a gross distort of the facts. His proposal during his day long speech did not win much support but had the result of pushing the convention closer to the “active” government he knew was necessary for national survival.
His experience as Washington’s right hand man during the war made him realize a stronger Union was necessary as it did most of those who actually fought in the revolution.
Newspapermen were in NO way “rounded up in mass” for any comments. The impact of the Alien and Sedition Acts were WILDLY exaggerated for political purposes by the Democrats and their lying press.
Not only that but Jefferson did the same thing. See the Croswell case in NY which provided Hamilton with his last great court case. He lost but the law on libel was changed so that truth was a defense.
