They dominate politics in the state, because they have the majority of the population. There is no way to split them up with other parts of the state that would result in more red wins. It would only cause more blue wins.Unless, during redistricting, big cities are cut up like pies with sections of urban areas married to suburban sections to create numerous competitive districts, I don't see how the machines can be taken apart or even how to prevent CHI and NYC situations where they dominate politics for the whole state
