Borden, Morton. "1801: Would Aaron Burr Have Been a Great President?"
Divergence: 1801 CE
What if: Burr did not remain aloof while the House of Representatives was breaking the Electoral College tie, and Federalists were persuaded to vote for him.
Summary: Burr would have become a Federalist, providing the party a charismatic leader, and Louisiana would have been conquered rather than purchased.
