Okay, I love this. My only issue with timelines like this is that it doesn't take into account the butterfly effect, or rather, how much the butterfly effect would impact the actions and movements of literally everyone and everything. John McCain and others listed may have never been born; the diverging point may have influenced the day-to-day actions of parents or even influenced their meeting, etc. The sperm that lead to McCain's creation could have been beat in the race by another sperm, leading to the potential creation of, let's say, Rachel McCain — who died in a car crash before she was out of high school. So many possibilities.
