In America you are not used to working as a coalition so here is how it works. 541 seats in Congress. Say the Dems get 260 seats, the Republicans get 94 and the new Patriot party get 187. On first inspection it would appear that the Dems have won and have control of Congress but they do not. Why.... because the Republicans and the Patriot party vote together as one conservative voting block giving them 281 on the floor so they hold Congress. Now between the Patriot party and the Republicans they can negotiate between themselves in terms of support.... you know “okay we will give you our 94 votes if you agree to vote for this legislation”. It is a way of giving every division a little bit of the pie. A coalition would work equally well for the Dems allowing AOC and the squad to split off and form a more socialist wing. The only risk I see is if Republicans decide to vote with the Dems in which case they are not really conservatives at all but I would suspect that they would not do that.

By just having Dems and Republicans you are making your system very black and white and it makes it virtually impossible for those factions on the outer edge of the party to get anything at all causing a rising sense of unfairness. It is time to think differently about how the system might work in the future. A Patriot party would be a good start.
