Well, current politics aside, I am wondering what else would be different like in economics, culture or international. Carter's role as Secretary of State was phenomenal.
It's why Jack Kemp brought him in and a good thing given how much worse things could've gotten in Rwanda...
There's an anecdote, confirmed in Donald Rumsfeld's book, that during one of the debates, President Ford made a remark akin to "there is no Soviet domination in Eastern Europe and will never be under a Ford Presidency". However, he was coughing pretty badly while speaking and when the moderator asked him to repeat his sentence he stated "the Soviet domination of Eastern Europe will come to an end under the Ford Presidency." Perhaps if he had said the former then that would have hurt him enough to cost him the election.
