/\ Puhleeeze... you're skipping all the way to Frederick Delacroix Robespierre and the 2nd Civil War?
WI no President Franklin might be a noobish cliche rivaled only by WI no Tesla Engine but still... the guy deserves at least a semi-serious answer.
No President Franklin requires a POD before he takes office in 1795. The logical one is that Washington isn't assassinated during the Whiskey Rebellion in October of 1794. That means the fabled "2nd Lightning Strike" in which Franklin decides to occupy the President's house after Adams has a heart attack fleeing the riots never happens. No special election, therefore no President Franklin. I guess you could also go the very easy route and have Franklin die of old age. He was up there in age by Washington's first term, if he knocked off in '89 or '90 instead of '98 it wouldn't have been a big surprise.
Without Franklin living in the President's house in Philadelphia there'd be no dead hooker skeletons buried in the basement. Which means the bodies are never found and President Burr isn't blamed and lynched by an angry mob soon after moving to Washington. Without that horrific event Red Lawn might have some boring name like "The President's Mansion", or "The White House".
And if Burr isn't wrongly killed for Franklin's atrocity then the Pinckney Dynasty may never happen. The first Thomas Pinckney and Charles Cotesworth Pinckney were OK, but we all know just how bad Thomas Pinckney Jr. was.
Let's not even get started on that war.
And so on and so on untill there is a United States of America that we might not even recognize. Without the Franklin murders would prostitution ever have been made so sympathetic? Can you imagine if France never gave us the Monument to the Fallen Harlot?
Can anyone of you even picture New York harbor without the Statue of Mary Magadelene?
