By the end of the session, the delegates would be shocked- none of the candidates had accomplished a majority in the electoral college, with Jefferson and Burr tied at 69- a single vote short of a majority. The news spread like wildfire from Washington, as the lame-duck Congress hastened back to decide the outcome of this highly contested election…
So the PoD is Georgia's fumble. The effect is that Jefferson and Burr are still tied, but have no majority. So the election goes to the House as OTL, except that the House has five candidates to choose from, not just two.
