Which President negotiated the Louisiana Purchase?

The Jefferson administration decided that the best way to assure long term access to the Mississippi would be to purchase the city of New Orleans and the nearby portions of Louisiana east of the Mississippi. Jefferson sent James Monroe and Robert R. Livingston to Paris to negotiate such a purchase.

(Napoleon made a huge mistake here)

I don't think he did, Mozart. He was in the process of losing Haiti, which would have been the stopping point for travel to New Orleans. Without Haiti as a supply stop, he would have been too extended. I think he made a wise choice. (Much better than he made in attacking Moscow. )

The Great Slave Rebellion of 1791

On August 22, 1791, slaves in the northern region of the colony staged a massive revolt that would eventually be known as the Haitian Revolution. Eventually the rebellion spread throughout the entire colony. The rebel slaves emerged as a powerful military force, eventually coming under the leadership of Haitian heroes Toussaint L'Ouverture, Jean-Jacques Dessalines and Henri Christophe. Master by 1800 of almost the whole island, Toussaint was invited to negotiate a settlement in 1802, but was seized and deported to France, where he died in captivity (1803)
The indigenous army, now led by Dessalines, defeated Charles Leclerc and the army sent by Napoleon Bonaparte in November 1803, and declared the former colony's independence from France, reclaiming its indigenous name of Haiti. The impending defeat of the French in Haiti is thought to have contributed to Napoleon's decision to sell the Louisiana territory to the United States in 1803. - wikipedia

Plus, Bonaparte's wars in Europe were draining the French money.

While it is certainly true that the European wars were costing Napoleon money, the two western possessions were very profitable. Haiti, until the French planters were driven out, supplied both sugar and coffee to much of Europe, and the New Orleans port was in the process of becoming one of the world's major ports. I feel that France would not have sold the Louisiana territory had Haiti not revolted, but without Haiti as a stopping point, New Orleans was too far from France.

I think Mozart meant James Monroe (as Livingston was certainly not President of the USA) - kudos for the response!

Interesting thoughts otherwise.
