Maybe if they go with a more obscure but still OTL person as president going forward we’ll just have an actor play them. Plenty of actors playing real people so far. The deepfakes are cool but seem like a lot of work, and limit you in your choices. As the writers have eluded to in interviews, there’s not going to be a library of archived footage out there for most people.
Also, if Ellen is going to be in DC, she’s going to need to be acting with people. Archival footage and phone calls won’t cut it.
I feel like maybe back before this season someone mentioned Dani as a political candidate. If anything, she seems like an even more likely person for higher office than Ellen at this point. Catching a tank is...cool, but an emergent narrative that you stopped a nuclear war- one confirmed by Reagan himself- that is a spectacular springboard. Especially if Gordo’s death means the truth about her arm comes out, that’s more fuel to the hero fire.
Plus (and I love Ellen), Dani seems like she really can enter a room and get people to listen to her and like her. She demonstrates that many times throughout the series. Whereas with Ellen I kinda feel like we have the writers giving us a series of white dudes who tell Ellen she has this power and suddenly it’s just true. (Of course what white dudes believe carries a lot of political weight, um, let’s say “in the 80s,” given the forum we’re in.)
If we are setting this up for the long haul, I can see maybe Ellen and Dani duking it out on opposite sides of the aisle in the Capitol for a while. It’d be melodramatic to have them face off for the presidency in season 4 or 5...but then we are watching a tv show here.
