What if the Republican Party had nominated Ulysses S. Grant again in 1880? Running against Winfield Scott Hancock could he have won?
There's also the question of whether Guiteau will focus on Grant and if his aim will be as good and the doctors as bad as in OTL. If so, that leads to little change from OTL.
Grant in 1880 means that roscoe conkling and the Stalwarts come out on top at the convention. Grant probably has to take a more moderate VP candidate in order to get elected. However, Grant probably manages to survive his third term, so no civil service reform is carried out.
Wasn't the only reason Garfield was assassinated because of his denial of an Ambassadorship to Guiteau in the first place? Would Grant be so inclined to deny such a request in the first place? Or would Guiteau even be interested?
Also, if Grant wins a third term in 1880, does he stick around in 1884 for a fourth?
Actually, Grant was the first president to recommend and attempt civil service reform. He appointed the members of the first Civil Service Comission, but Congress did not support him.
