If Abraham Lincoln wasn't assassinated, I'd assume he wouldn't be interested in running a third term. In this scenario, who would Lincoln want to be the next president and who would likely get the Republican nominee in 1868? I am excluding Ulysses S Grant as the falling out between him and Andrew Johnson played a noticeable part in eventually being chosen in OTL 1868, and of course to be different
How do you think your choice would impact the country if they became president in this scenario, or would the Democrats have a chance of winning this one?
