Lincoln didn't agree with this bill because he thought it was too harsh. He had a more lenient Ten Percent Plan, which allowed southerners still hold/run for office,unlike the Wade-Davis Bill. Unfortunately Lincoln was assassinated before the veto was official, and the Ten Percent Plan was put in effect.
Answer:
The difference between causation and correlation, is that causation is when one event causes another one to happen. Correlation is not causation because two events can correlate, but that doesn’t mean that they caused each other. One example of causation could be because there was a large run of salmon, he got the most he has ever caught. One example of correlation is that there was a large run of salmon, and coincidently the new mayor is a great fisherman. There being a large run of salmon did not cause the new mayor, who is a good fisherman, to be elected. That’s a little confusing, you may have to read it more than once.
