The court would not have half the power it does now, and provisions would be put in that Congress can over ride any decision by the courts.
There would be a provision forbidding the Senate from being able to make a rule for the filibuster, and that the majority wins period. This way the people through the vote decide, and no minority can ever rule.
There would also be a provision that there is a guaranteed, 100% absolute right to vote that can never be restricted or taken away.
There would also be a provision prohibiting any state legislature from drawing unfair districts, that is coded in law, that no federal court could rule against.
There would also be no electoral college.
