Yes. Grant was a good and decent man.
He performed so bad in his second term that the next four consecutive presidential elections were decided by razor thin margins and three of those four by less than 1% in a popular vote difference.
The exception was 1876, where Tilden, the Democrat candidate, actually won the popular vote by 3% but lost because 15 electoral votes from three former Confederate States (Louisiana, Florida and South Carolina) were still under military occupation and enough former Confederate soldier's ballots were invalidated to make the difference.
This action raised enough of a fuss that Hayes agreed to serve but a single term and end the military occupation as soon as he took office. Hayes was good to his word and went on to serve a very capable four years and undo much of Grant's damage.
