Does this assume a Confederate Civil War victory?
Also what is the party's view on Stephen Douglas and popular sovereignty?
I guess the AL Democratic Party stays Dixiecrat and the American Independence ticket never happens in 1968, which should hand the WH to HHH, who loses in '72 to Rockefeller, who beats McGovern in '76 , VP Howard Baker loses in '80 to Carter, who loses in '84 to Reagan, and VP HW Bush loses to Clinton in '92, as you can see, this quickly becomes problematic, as we have just switched a bunch of Presidents, HHH's continuation of LBJ's Vietnam, would have been disastrous, also Rockefeller does win the WH, along with Reagan, creating contrasting GOP visions, lastly with a Confederacy, we have to take out Howard Baker, Jimmy Carter, HW Bush, and Bill Clinton, and replace them with Northern Democrats. This quickly becomes problematic.
Kamala Harris is the only one who can win PA due to the fact that Beto O'Rourke is polling poorly in Louisiana. Joe Biden will lose California.
