Oh, wow, I am thoroughly impressed by the level of detail and effort they have put into this, and I am also thoroughly impressed by us roleplayers going "Ohai!" instead of going "RP is wrong".
They've done their old Fed chron reading, picking up on the two main parties, the Progressors and Sociocrats, as well as the Unionists (with a Brutor chairwoman too, as per the chron), and even had their own Nationalist flavour...I imagine the more moderate successors of the Ultra-Nationalists.
There was also the "Federal-Populist" party mentioned during the Roden election campaign, with Garioss, I imagine for the sake of consistency it could be the Federal Populist Party...I would say they are taking extensive liberties in the fact of RPing the leaders of the parties BUT with Blaque and Foiritan gone, and any mention of parties in recent PF has sort of waned so v0v (EDIT: Nvm, Alain Octirant mentioned the "populists aren't going through with it")
I watch with interest!
EDIT: Aha, they are not claiming to be Senators, but non-politician members of the respective parties. Fair play.
