What would be the effect of a Tilden victory in 1876, he had won the popular vote. Ironically, both Hayes and Bush won the Electoral College vote based on a disputed popular vote in Florida. The day after the 1876 election it appeared that Tilden, the Democrat, had won, but Republican election boards in Louisiana, South Carolina, and Florida, where attacks by white supremacists against African American voters was widespread, invalidated enough votes seemingly to swing the election to Hayes. What would happen to Reconstruction if the Repuplicans don't make concessions to get Hayes into office?
