Political what-if: A second Constitutional Convention

[classicdrogn]

For my part, I'd like to permanently and explicitly break the two-party system. Maybe make it so members of a single party may not hold more than 40% of any particular voting body? Whether the body as a whole, or how many of them show up on a particular day to vote. That would still allow for committee sizes as small as 5. This would open up the possibility of a minority deciding not to participate and deadlocking things for lack of a quorum, though, so maybe allow for a 60% supermajority of the total body to make one-time-per-vote exceptions in order to deal with obstructionist behavior.
