The mentions recently of Andrew Johnson as the first President to be impeached have left me wondering: Suppose he had never been President at all? Suppose JW Booth had been stopped, and Lincoln had lived out his second term? Johnson would not have been able to sabotage Reconstruction, and Lincoln would have been a force for reconciliation and progress. Where would we be today if Lincoln had had four more years? Discuss.
Well there are three possible sets of circumstances to deal with.
1. No-one ever attempted to assassinate Lincoln
2. Someone stopped Booth before he could attempt the assassination
3. Booth attempted the assassination, but Lincoln survived
IMO, the timeline might proceed very differently depending on which of the above scenarios we are discussing, but generally, thing might be different today than they are in reality.
Generally speaking the following might have happened IMO...
Reconstruction might have gone a lot more smoothly and been a lot more forgiving of the south (more like the way the US treated Japan after WW2 than the way Germany was treated after WW1).
We may have seen the Whigs in political power in the South, with Lincoln's support, as they were seen as reluctant secessionists rather than the Democrats who were enthusiastic.
The Civil Rights movement might have happened a lot earlier, say, in the 1920s, and have been far less widespread. It is even possible the there might have been no Civil Rights movement at all because the emancipation of slaves as well as their suffrage, might have happened a lot sooner - and segragation might never have happened.
Remember, the radical Republicans at the time wanted to confiscate the plantations and divide them among the former slaves - that would have been a disaster, and may eventually have led to second Civil War.
There are people in the South who, after almost 160 years, are still deeply resentful of the way in which the region was treated after the Civil War. If Lincoln had lived, and he helped to make that treatment less harsh, then the deep seated resentment we see now might either be far less than it is, of even not exist at all.
With all of the above a possibility, if we fast forward to 2020, American society might not be as racially divided as it is now, because much of the South's current resentment of the North would not be there to fuel it.
EDIT: I could add more about other aspects including education and the economy of the South, but I'll wait to see if others want to join the discussion. So far, there have just been silly remarks so I'm not wasting time on it of no-one wants genuine discussion.
