Let's say Reagan successfully primaries Ford, and takes the GOP nomination four years earlier than IOTL. I'm not sure specifically how to do this but I'm thinking a few years down the line. As he suggested IOTL, Reagan picks Richard Schweiker as his running mate. Somehow, Reagan manages to get himself reelected in 1980 perhaps defeating Senator Edward Kennedy? Anyway, come 1984 what does the GOP primary race look like? My guess is Vice President Schweiker gets the nomination but I'm not entirely sure.
What might a Schweiker vs. Hart race look like after 16 years of Republican control of the White House?
Also, what happens to George H. W. Bush? He isn't going to be Reagan's vice President, and he certainly won't run in 1980. Secretary of State Bush?
