Just played 2WRW a while back before the update broke everything, and....
Frankly NGL but honestly....I found the US skeleton the weakest part of 2WRW.
For those that haven't played....bascically the NPP implodes no matter what. Now I know the NPP was always contentious, and I am aware there is a TNO sequel mod(The Fading Order) that deletes the concept entirely, but the way this is done is frankly an extreme deus ex machina to revert US politics back to democrats and republicans. There is no organic buildup to the implosion of the NPP unless you run a pure democrat and republican game.
Basicallythe Extremists are eventually booted out, and Schafly and Jackson face so much obstruction in congress that they never get anything done and ragequit. Big name dems and republicans overwrite everyone for 76.
Now perhaps it's my own regret at suggesting Yockey in the NPP in the first place, but Yockey and Hall leading the NPP to collapse makes sense, especially since I think the more "out there" devs that had the whole "Hall peacefully introduces socialism with American characteristics" and "Yockey creates a violent genocidal state or gets couped by weathermen" crowd left long ago(whether it's because of the Ma Mod split or the later split, I'm not going to entertain) and especially with a closer relationship to TNO devs, you'd kinda need to shift things a bit closer to hard alternate history(ie: IIRC the Latin America team had to drop Serrano and the cursed colonia dignidad route for Chile for simular reasons), so realistically those candiates have no chance. That said, I do feel that Yockey might actually have to be removed from office by more external means(like an arrest by the military when he tries to do something really gamer, the courts and congress say no, and he tries to stir some shit up). I know that the difference is that TNO is not planning to intergrate 2WRW anytime soon but I do feel that working closely with TNO, and given the general aversion of HOI4 mainstream mods outside of KR in having an radical right or left America of any sort
However for say an NPP that managed to govern 8 years after Harrington? Or an RFK-->Scoop run? I think things would be much different since we'd have the NPP actually governing for 12 years. I can understand the arguement that the duopoly-oriented structure can't support the NPP and its inherent contradictions would tear it apart but frankly? It would have meant that the NPP, before it dissolved, would have significantly changed the overton window of the R&Ds that the R&Ds slowly have to pander more to them.
It would make more sense if we had Schafly or Scoop win in 72, but as the NPP fractures, they rely more and more on the side of the R-Ds that would agree in their agenda, shifting either the dems to a more progressive but hawkish end or the Republicans to a more far-right but OFN skeptic end. This culminates in the NPP slowly folding into the R-Ds rather than collapsing, and we'd get Scoop run as a democrat in 76 or Schafly run as a Republican in the same election year(and they'd be pitted against for Scoop someone who's more isolationalist but more to the right on the GOP side, and for Schafly a explicitly "unite to stop far right" sort of candidate)
Likewise if we had Harrington leaving office in 1976, the idea could be that he slowly learns to rely more on the dems(the DSA was always pro-dem lesser evilism in a way anyways) and by shifting the American political environment as the progressive NPP folds into the dems, the dem nominee in 1976 would be very left wing(like a Henry Wallace sort of person) because of the merging of the NPP-P and the dems.
There's also the fact that you get the same candiates regardless when honestly what R-D candidates show up in 76 when realistically, Ted Kennedy would honestly work as a post-Schafly(let's say he's the dem nominee when Schafly and NPP-right wing flips to the GOP) or Post-Yockey sort of "this time the camelot legacy will save America" sort of person(or alternatively the 76 dem candiate after a mostly successful RFK run against George Romney on the basis that they'd do better), and Birch Bayh realistically would only work for a post-MCS run; to perhaps abolish the electoral college in order to stop the radicals seeping into the dems or the gop from "corrupting" the political establishment.
And a quick nitpick, frankly having Reagan as a republican candidate in TNO is literally something the mod wanted to avoid.
