*The carriage breaks down and they have to go another day
*Grant accepts the invitation and goes with the Lincolns
* Booth gets drunk and fails to kill Lincoln
* Lincoln leans forward before Booth shots him
* Booth is caught by Rathbone before he kills Lincoln
* Johnson is assassinated as well
* Steward is assassinated
How would these PODs affect the US? If Lincoln survives, what happens next? If booth misses his chance, does he try again?
