In OTL the Election of 1876 in the United States featured all kinds of shenanigans: Democrats putting the picture of Lincoln on their ballots to trick the illiterate, Republicans and Democrats both stuffing ballots, and ultimately an extra-constitutional deal rewarding 19 disputed Electoral Votes to Hayes so that he won the election by a single EV despite Tilden (officially) earning 51% of the popular vote.
Let's sidestep all of that unsavory history with this POD: instead of losing California by less than 3000 votes, Samuel Tilden wins the state by an (undisputed) razor-thin margin. This gives President-Elect Samuel Tilden 190 EV even if all the disputed votes are left by the wayside.
How does this affect the End of Reconstruction and the beginning of the Gilded Age?
