One possibility is that Carter would have continued to pursue his policies of economic austerity and deregulation, which could have led to a continued economic slowdown and high inflation. This could have further eroded public confidence in Carter and the Democratic Party, making it more difficult for him to win re-election in 1984.
Another possibility is that Carter would have changed course and adopted more expansionary economic policies, which could have stimulated economic growth and reduced inflation. This could have improved his chances of re-election in 1984, but it could also have led to higher budget deficits and a decline in the value of the dollar.
It is also possible that Carter would have faced challenges beyond his control, such as an international crisis or a natural disaster. These events could have made it difficult for him to focus on domestic issues and could have further damaged his chances of re-election.
Ultimately, it is impossible to say for sure what would have happened if Carter had won the election of 1980. However, the scenarios outlined above provide some possible outcomes that could have occurred.
