The initial premise and POD was a different second marriage keeping him in the Democratic camp. I still wanted him in California politics so Nixon successfully defeats Brown in his 1962 gubernatorial bid but (after likely being forced by the party to run again in 1964) is succeeded by Reagan in 1966. Without Nixon or Reagan in Republican politics 75.47% of the vote is up for grabs. Beyond the three Rs (Rocky, Romney, and Rhodes) there's Chuck Percy, a less tarnished Barry Goldwater, and all those favorite sons. As I began with Reagan winning 1976 as an outsider, there's obviously some scandal plagued administration from 1969-1977 or 1973-1977. If I had to give a list, it would be something like this: 37. 1969-1975: N. A. Rockefeller (R-NY)† 38. 1975-1977: Claude R. Kirk Jr. (R-FL) 39. 1977-1985: Ronald W. Reagan (D-CA) 40. 1985-1989: Lido A. Iacocca (N-MI) 41. 1989-1993: William J. Clinton (D-AR) The idea of Reagan being a Democrat though made me think about a world where all the Republican presidents (or, alternatively, all the nominees) became Democrats instead, and just how both parties could develop with/without those personalities in them. And a vice versa scenario where the Democratic presidents/nominees are Republicans. So if I continue building the scenario I'll do so from that direction and maybe incorporate a Democratic Willkie, Dewey, Eisenhower, Nixon, etc!
