I think reconstruction would have been a whole lot more favorable to the south had Lincoln lived. His death brought a lot of people to power who sought nothing more than revenge.
Few in the south hailed Boothe as a hero both because his was a cowardly act and because they knew it would bring harsh treatment on the south.
I should leave making this point about "With malice toward none, with charity for all" to you :P
Lincoln would have shipped African-Americans to the Caribbean and Liberia. So yes it would have gone real smooth. /sarc
