i'd imagine party block where 1 large party is in an alliance with many small parties, the main party gets increased support in areas where it's close and the smaller parties get influence in politics
the blocks:
Greens - Lead by the green party and the smaller parties are regional green's, transit parties etc.
Labor - lead by the left wing part of the former democratic party smaller parties are probably something lead by bernie if he's not leading the party, vermont progressives etc.
Centrists - Lead by a merger of Forward and the center of the democratic party and smaller parties are gonna be mabye one lead by elon musk and etc.
republican - lead by the old guard and other non alt-right republicans smaller parties are american solidarity and etc
Libertarians - Lead by the libertarians smaller parties include non american libertarians etc.
Constitution - if the constitution doesn't become a smaller party of the alt right group it's small parties could be nationalists and Cristian
Alt-Right/Nation - Lead by the alt-right or trumpist republicans smaller parties could be the progressives if they don't become big and some far right parties etc.
there could also be an state independence and minority rights - this could be the exception to party blocks and would be composed of vermont, texas, california, alaska and hawaii independence parties and latino, black and LGBTQ+ parties
