I know the chances of it happening are slim, even a bit ASB, but let us say that on March 30th,1981, John Hinckley's assassination attempt on Ronald Reagan succeeds, and later that day before he can take to oath of office, George H.W. Bush dies in a car crash.
Now, to my knowledge, this would make Speaker of the House Tip O'Neill President, who was a Democrat and critic of President Reagan.
How would people in America and elsewhere around the world react to the death's of both the President and Vice-President on the same day?
What would a Tip O'Neill Presidency look like? Who would he pcik to serve as his Vice-President? Would O'Neill run for a term of his own in '84? Granted he would have been in his 70's by then, but he was only one year younger than Reagan was, so age might no have been a problem.
What impact would this have on American politics, as well as future Presidents?
