The “winner-take-all” nature means only the largest parties consistently win seats, marginalizing smaller groups. This structural advantage makes it difficult for new or minor parties to gain significant representation.

Independents are not a smaller group. They are 56% They are the bigger group and vote D or R because they have no other option. Independents can replace the D party.

The US isn't a lost cause. Proportional representational is only made harder by people like you, who scream till they're blue in the face that change is impossible while being surrounded by constant change.
