In OTL, Lincoln's first Vice President, former Maine Governor and Representative Hannibal Hamlin, was replaced as Lincoln's on the running mate by Southern Unionist and War Democrat, Tennessee Military Governor Andrew Johnson; who would go on to become the 17th President of the United States after Lincoln's assassination in April 1865.
What I ask is the following, presuming Lincoln still wins re-election and still gets assassinated by John Wilkes Booth, what would have happened had Hannibal Hamlin been kept on the ticket and eventually became Lincoln's successor upon his death, how would have he governed? how would he handle Reconstruction? could he have a won a term of his own right in 1868; and if so would it derail the political career of Ulysses S. Grant?
