Imagine no Reaganism. No Ronald Reagan.
President Jimmy Carter wins reelection in 1980.
Who do Republicans go with in '84?
Implying the Republican nominee was somebody else in 1980? If Carter defeats a non-Reagan moderate then maybe the nominee is a conservative like Jack Kemp. If he does defeat Reagan under OTL 1980 conditions then it probably discredits Reaganism for a long time. My guess is that the nominee in 84 is a moderate but not Bush since Bush would be discredited from being on a ticket with Reagan.
